Chapter 3 - Exponents 

We all know that if I add  2 + 2 + 2 + 2 + 2 + 2 ( six times), and if I multiply 2 x 6 ( two multiply by six ); It will give me same answer. ( 12)

Similarly, if I multiply 2 x 2 x 2 x 2 x 2 x 2, it will be the same as . Two is called Base and Six is called Exponent. We can call it as two exponent six. 

Let's have a look at the few examples below.
