Science and Mathematics are subjects based on both theory and practice. However the significance of theory is more because the theory came into being first and then it was proved by practical applications. Formulas form a big part of science and mathematics theories, theorems, or a law as may be quoted. There are formulas in both mathematical and science subjects such as **Algebra formulas****, ****Physics formulas** and **Geometry formulas****.**

Formulas are a definite way to prove the theories that were invented by great scientists from all over the world. Albert Einstein’s law of general relativity and Sir Isaac Newton’s three laws of motion made lot of progress in the science and mathematical field.

**Formulas are simple ways of representing things that are otherwise difficult to represent. For instance, the Binomial theorem which is an Algebra formula:**

(a + b) 1 = a + b

(a + b) 2 = a2 + 2ab + b2

(a + b) 3 = a3 + 3a2b + 3ab2 + b3

(a + b) 4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4 …and so on…

**The difference between equation and formulas:**

**Equation represents that two sides of the ‘=’ left and right are equal**

**For instance, x+2=6**

*In this the left side: x+2 is equal in value to the right side that is 6*

**On the other hand, formulas are equations too but they define the relationship between two different variables that actually represent certain value/number.**

*For instance, V=IWH*

*In this V symbolizes volume, I symbolizes length, W symbolizes Width and H symbolizes Height*

Another difference is that a formula will have more than one variable. In the above formula example, there are three variables (V, I, H and W); whereas in the equation example there is only one variable. This is because an equation is not a formula in the first place.
