How Not To Solve Math Problems?

Solving math problems is a persistent head ache for kids and parents. Many deem it a chore due to the difficulties they face in the process. The fact is many do not know that they are solving math problems wrongly and do not know the ways to solve them correctly.

Do students solve Math problems wrongly?

Yes, they do! But how and where do they go wrong?

Rote memorization

From the childhood of kids, they have been advised to follow the rules instead of practical methods in solving problems. When kids try to apply rules instead of practically approaching a Math problem, it becomes a constant struggle for them to pick up Math skills. Instead they can come into the real world, get to know life situations while trying simple Math problems.

teachers

When it goes to an extent, kids know how to apply abstract thinking for solving Math problems and go ahead with that. For example, Geometry expects students to visualize problems and approach them with creative imagination. When students try real life examples for visualizing Geometry problems, they are able to do it at their best. Online math tutors help students in this matter with their examples, real life samples, drawings and models.

Deeming problem solving skills as an inherent talent

Problem solving skills in Math are not inherent and inborn. They come out of practice. When a child enters Pre Calculus or Algebra stage, he finds it difficult to cope with the subject and gets stuck in problems. Teachers and parents think it is somewhat inherent to solve problems and consider it as a talent in kids. Not so. It is good if a child gets stuck in a problem. For, it helps him know the way out of the problem, solving it successfully. So, problem solving is a matter of practice and not something inborn.

Parents’ role in helping kids solve math problems

Parents should be positive and encouraging while helping kids in Math problems. They should not panic and create anxiety in the minds of kids. They should understand that problem solving is a natural process in life and Math problems reflect that. They can reorient their skills while helping kids or contact tutoring centers that offer help. Suppose the child struggles with geometry homework, they can seek math homework help from expert tutors online and redeem their kids’ faults at once. It is parental care and encouragement that drive away Math fear from the hearts of students.

Parents can go in for resources like Math puzzles, quizzes and games and accustom their kids with such practices from day 1 of their Math learning. Kids find Math fun and interesting and will sit with Math problems even when they are stuck in it. It is because doing Math becomes their way of life by this time. Even when they get to do assignments in complex topics as they find in Geometry, they take it as a challenge and do it with ease. Suppose, kids struggle even then, parents can seek virtual resources like math assignment help and resolve the struggle.

Summary

So, doing math is not the issue but whether you do it rightly or wrongly is the matter. Approaches and practices decide the matter and those who understand this fact come out successful in math problem solving.

Simple math tricks to boost your problem solving skills

Squaring a 2 digit number that ends with a five

In case you wish to square a two digit number ending with the number five, all you need to do is the following:

  • Multiply the 1st digit with itself and add a one to it and put this at the beginning
  • Add 25 at the end of this number and the result is ready.

For example, take 35. To square 35, all we need to do is multiply 3 to itself and add one to the result. This gives us 9+1 = 10. We just need to add 25 at the end and we get 1025 which is 352

Tip Calculation

This is something that everyone encounters on a day to day basis. A 15% tip is the standard and the next tip you or your friends or parents need to calculate a 15% tip, here’s how you can do it in a simple manner. 15 = 10 + 5. Just find out the 10% of the number (which is not but division by 10) and halve it. Now add the 10% and its halved number and your tip is ready.

For example, if you have to leave a 15% tip for 65$, here’s how you calculate it. 10% of 65$ is 6.5$. Half of 6.5$ is 3.25$. Thus, the total tip is 9.75$

There are many more such tips and tricks that students can use to ease the strain and time involved in working out complex arithmetic. Having these tips handy is sure to same them time in exams as well as homework and these work out to be the best math homework help a student can ask for!

7 Tips for Finding the Right Online Math Tutor

How do you know your child needs math assignment help? Some of the more obvious signs are falling math grades on your child’s report card or on individual math assignments. A change in attitude toward math can also indicate difficulties. If your child loved math last year, but suddenly dislikes it, he or she could be experiencing difficulty mastering new math concepts.


Math difficulties can arise at any stage of the learning process.

Working with a math tutor, including an online math tutor, should be explored as soon as you realize your child is having difficulties. Throughout school, math lessons build on what was taught before, and failing to master a single concept can result in multiple math difficulties later on. Once you make the decision to work with an online math tutor, how can you be confident you have found the right one for your child? Here are 7 tips for finding the online math tutor that will benefit your child most.

1. Look for a Tutor Who Specializes in Math

Even if your child is in elementary school, it’s worthwhile to look for an online math tutor who specializes in math. While there are general tutors who can offer math assignment help, a tutor specializing in math is more likely to have the depth of knowledge necessary to understand the specific concepts that hold children back and how to address them.

2. Find a Tutor Whose Schedule Works With Your Child’s

The great thing about the internet is it never closes, and you can interact with someone on the other side of the world if you want. That said, it’s important to find a tutor who will be available during the hours your child works on math. If you’re considering an online math tutor from several time zones away, ensure his or her schedule meshes with your child’s before committing.

3. Choose a Tutor Willing to Work Interactively on Concepts

Math assignment help should be interactive. A good online tutor doesn’t simply lecture or present concepts, but interacts with students: “What do you think the first step should be?” Your child’s tutor should be able to develop a working rapport with your child, striving to understand his or her questions and difficulties so as to address them most effectively.

4. Look for a Tutor Willing to Explore How Not to Solve Problems

Sometimes a child needs to be shown how or why what might seem to be a solution doesn’t actually work. A great online math tutor understands how something might intuitively look right, yet not be. There may be occasions when a tutor needs to go through the wrong procedure with your child to show where and why problems occur.

5. Select an Online Tutor Who Uses Plenty of Visual Aids


Online math tutors should have easy access to helpful visual aids.

Diagrams, pictures, animations, and other visual aids can be tremendously helpful. For example, a child having difficulty with fractions may have an easier time if concepts are demonstrated through something he is familiar with, like LEGO. Try to choose a tutor who knows where to look online to find GIFs and other visual aids that help explain mathematical concepts.

6. Pick a Tutor Who Knows How to Assign Subject Matter in Context

Some children, for example, have no trouble applying concepts like basic arithmetic operations, but have trouble knowing which one to apply in word problems. Other children may not be motivated to perform an arithmetic operation without some sort of context (like a story problem) in which it makes sense. Your online math tutor should take time to learn how your child learns.

7. Try to Find a Tutor Who Is Open to Feedback

You don’t want an online math tutor who is resistant to feedback. After all, the goal is to help your child master important concepts. Knowing what works well and what doesn’t is important for an online math tutor in order to provide the best possible service. Discuss feedback before hiring an online math tutor to ensure the one you choose is open to suggestions and discussion.

In Conclusion

Hiring an online math tutor is an option many parents didn’t have when they were learning mathematics, and it can make a world of difference in your child’s ability to master mathematical concepts and keep up with what is expected of him or her. Know what to look for in an online math tutor, and you can be confident that when your child needs math assignment help, he or she will have access to someone who understands math, understands your child, and is willing to work with your child’s learning style. Are you interested in hiring an online math tutor for your child? Tutor Pace can help, and we encourage you to get in touch with us at your convenience.

Math For Advanced Level; Algebra Geometry And Calculus Advanced

mathclass

Math is a combination of many branches such as Algebra, Geometry and Calculus, but math does not quite stop right there, we have levels to each branch of math such as beginners and advanced. The advanced level math usually needs more attention and practice to master it. If you are confident with the basics and know all your formulas then the advanced level math is the next step to beginner math topics. Today let us look at different advanced level math questions in areas such as Algebra, Geometry and Calculus.

Advanced level Algebra

Algebra consists of different algebraic expressions and equations. Algebra has different kind of questions to solve. Mentioned below are few such questions which will give you an idea about how to use the basics of algebra to solve advanced level questions:

Solving linear equations with one variable:

Find the value for x in equation 4 (2x – 3) = 5 (2x – 8)?

Here the unknown variable is x. Since there are numbers in front of the brackets, distribute the numbers as shown below:

math1

Here we have x on both sides of the equation, bring all like terms to the same side of the equation and solve for x.

math2

As show above the equation reduces to 2x = 28. Divide by 2 on both sides of the given equation. This gives x = 14.

Did you follow the solution to the question above? Now let us look at solving an inequality. Solving inequities play an important role in algebra. An inequality is where there is a comparison and is represented by a less than or greater than symbol. The solution to the inequality are usually represented on a number line, so as to represent all the possible values for the variable. Follow the given example below:

Solve the given inequality 3 (2 x + 8) > 24?

Look at the question we have greater than symbol here. You have to solve for the unknown variable x and find all the possible solutions for it. For the given question above, divide both sides of the equation by 3 as show below:

math3

Now the inequality is reduced to the form 2x + 8 > 16. The next step is to solve for x. follow the steps below:

math4

The inequality is now reduced to x > 4. Look at the symbol separating x and 4 it’s a greater than sign not greater than equal to. This implies that the number 4 is not included in the solution. Hence the solution of x contains all the values greater than 4 such as 5, 6, 7, 8…….. This can be represented on a number line as show below:

math5

The advanced level algebra consists of many other subtopics such as quadratic equations, solving two variable equations using substitution and elimination methods and many more. The key to success for solving all such questions is practice and knowing the basics of Algebra.

Advanced level geometry:

After algebra let us look into geometry and some sample question. Geometry is one of the favorite topic for all the students especially when you are in the elementary school, it could be because of learning different kinds of shapes. But geometry does not quite stop there, as you go to the higher grades you need to tackle the advanced level. Let us look at two examples on how the basics of geometry can be helpful to solve the advanced level geometry question.

 Find the area between the two shapes for the given geometric figure:

math6

The given diagram is a square inscribed in a rectangle. Let us recall the formula for the area of the rectangle = length x width. Using the formula, the area of the rectangle = 10 x 8 = 80 square inches.

Now the area of the square = side x side. Using the formula, the area of the inner square = 4inches x 4inches = 16 square inches.

The area between the two geometric figures is obtained by the difference in the areas.

Hence, the area = (80 – 16) square inches = 64 square inches.

Did you follow the solution? Great! The next question you will see how the sum of the angles can be used to find the missing angles of the triangle.

The sum of all interior angles of a triangle = 180 degrees. This fact is very commonly used in solving many geometrical questions. Knowing the angle measures helps you classify the different kinds of triangles such as equilateral, scalene, and isosceles.

In the given diagram, find the value of v and the angles of the triangle. Classify the triangle?

math7

Sum of all the angles of a triangle = 180 degrees.

Adding all the angles of the triangle v + 2v + 60 = 180. This gives 3v + 60 = 180.

Solve for the variable v, follow the steps below:

math8

The angles of the triangle are v = 40 degrees, 2v = 2 (40) = 80 degrees and the third angle is 60 degrees. Therefore, the angles of the triangle are 40, 60 and 80 degrees. Since all the angles of the triangle are different. The given triangle is a scalene triangle.

Advanced level Calculus

The next branch of mathematics which is very important and plays a major role in high school and college level math is calculus. The students are expected to know pre-calculus before stepping into calculus or advanced calculus. Calculus starts off form the basics of functions, domain, range and steps into differentiation and integration, which are the advanced level topics.

Let us take a quick look at few solved calculus questions:

Find the derivative to the function f (x) = 3x3 – 5x2 + 10?

Here before finding the derivative of the given question there are some formulas of derivatives which are expected to be known. Learn from the diagram below:

math9

Did you recall the formulas? Now apply the power rule to 3x3 and -5x2. Since 10 is a constant the derivative will be zero. Take a look at the diagram below:

math10

The answer f’(x) = 9x2-10x.

Taking a step forward, let us solve a derivative question involving logarithms and exponential functions.

Find the derivative of the function f(x) = x5 + 2ex + 3log x?

For the given question you can apply the power rule to x5, exponential rule for 2 ex and logarithmic rule for 3 log x. Use the formulas as mentioned in the diagram below:

math11

Applying the formulas to the given function:

math12

Hence the solution f’(x) = 5x4 + 2ex + 3/x.

Here are some methods:

1. Squaring of a number ending in 5.

Find the value of 352?

The number ends in 5 the square of it should always ends with 25. In front of 25 place 3 x 4 = 12. That is the product of 3 and its consecutive number which is 4. Follow the diagram for a better idea:

math 1

Did you follow the trick? The more you practice, you will be able to solve these questions in one step. Now let us look at the longer version for the same question:

math 2We get the same answer!

Take a look at one more example to master the skill.

Find the value of 952?

Here since the number is ending is 5, the square will end in 25. In front of 25 place the product of 9 and 10. Follow the diagram to apply the method:

math 3

The answer is 9025.

This can be applied to three digit numbers as well. But the point to note is the number should end in digit 5.

Find the value of 2052?

The number ends in 5, so the square of the number will end in 25. For the next step follow the diagram below:

math 4The answer for the three digit multiplication for 205 x 205 = 42025. Check the answer in the longer method as well you will get the same value. 2. Square of numbers between 30 to 70? In this method we can find the square of the number between 30 and 70 within no time. Usually it takes us the regular multiplication method or the calculator to find the square of a number. Imagine, if you can solve it in the mind in a fraction of few seconds. Find the value of (51)2? Step 1: Find the difference between the given number and 50. You get 51 – 50 = 1. Step 2: Now add the difference to 25, this gives 25 + 1 = 26. (These are the first two digits.) Step 3: The last two digits of the square will be equal to the square of the difference.

Follow the diagram for the next step:

math 5

Find the value of (64)2?

Step 1: The difference between the given number and 50. You get 64 – 50 = 14. (As 64 > 50)

Step 2: Now add the number 14 to 25, this gives 25 + 14 = 39.

Step 3: Calculate the square of the difference 142 = 196.

For the last step follow the diagram.

math 6

Find the value of (44)2?

Step 1: The difference between 50 and 44. You get 50 – 44 = 6. (As 44 < 50)

Step 2: Now subtract the number 6 from 25, this gives 25 – 6 = 19. (First 2 digits of the square.)

Step 3: Calculate the square of the difference 62 = 36. (Last 2 digits of the square.)

For the last step follow the diagram.

math 7Hence the number is 442 = 1936. (Practice this method for more numbers.)

3. Subtracting any given number from 1000.

In this method for the given number that has to be subtracted from 1000, subtract the ones place by 10 and the remaining numbers by 9. For a better idea try to follow the examples shown below:

Find the value of 1000 – 356?

How to Study For a Math Test the Night before the Exam?

How to Study For a Math Test the Night before the Exam?Many student try to study for a math in the same way as they would study for geography exam. But in a real world they are not the same subject. You need a structural way to memorize formulas and equations and the best way to learn them by using and practice math. Here are few tips that will help you plan on how to study for a math test the night before and help you with getting a higher grade.

Remember your goal

First of all you need to decide why are you studying? Do you want just a passing grade, maybe a B or even to ace the exam? Answer this question and stick to your decision. Many students think they want to pass the exam with a C but the more they study, the more they realize that they would prefer an A. Getting an A is great, but still it requires much more effort than a B.

Do not try to learn anything new

If you attended classes as you should have, you probably know a few things already, you just don’t realize that yet. Have a quick look through all your notes and study materials and decide what things you already know. Once that is sorted, you can concentrate on knowing them better. Learning new things the night before the exam can be tricky, as sometimes the stress and panic can make your brain forget the things it already knows to make space for what you are learning. Even if you know just 60% of that class, as long as you know it very well, you are guaranteed to pass.

Stay away from distractions

Many students tend to waste time while studying. It can be either because of their friends, taking small breaks, not finding a pen or getting hungry. Make sure that before you start studying, all these distractions are out of your way. Eat well and healthy, make sure you have all your study materials and resources and take care of any other physical needs you may have. If you do this, you are less likely to lose focus during your study time. And if you like listening to study music, make sure that it is free of lyrics, as listening to 50cent is definitely not a wise choice.

Use note-cards to remember formulas and techniques

Note cards are a student’s best friend when it comes to exams. These are the most simplified form of your actual course notes. Try to keep them as clear and short as possible, without any examples or complicated sentences. Once you have these note cards done, use them wisely, as they will help you see what you know and don’t know.

Get some sleep

A lot of students think that studying the night before the exam, it actually means all night. They couldn’t be more wrong. The brain can only concentrate for so many hours, so if you study for an entire night, you will be tired during the exam. Drink lots of water and keep few snacks items with you before you study. This will stimulate your brain and will help you memorize and work on math problems.

On the day of the exam

Plan to show up at least 30 minutes earlier than the exam time. Keep calm and do not panic if someone tells you something you don’t know. Most likely, they did the same as you, learned very well what they already knew. Also, try to review once more your note cards. Start the exam with the questions you already know and leave the rest at the end. Always keep calm and stay positive and confident of your final preparation for math and focus on one goal that you can do it. Good Luck!
