Variable

The “letters” in an equation are the variables.

A variable is a symbol part of an equation or next to a number that we don’t know the value of yet

The variable nature of letter's sizes makes them very difficult to manage.

Example 1

`a^2+9^2=100` 

In the above equation “a” is the variable.

 

Example 2

`a^2+b^2=c^2` 

In the above equation a, b and c are all variables.

 

Example 3

`136=\pir^2`
