Exponent

An exponent is a small number written with another big number that tells how many times to multiply the big number by itself. It looks like this:
3²

and this means 3 x 3 which equals 9.
The little 2 is the exponent.
It DOES NOT mean to multiply the 3 by 2. It means to multiply the 3 times itself.
Here's another one: 4³ = 4 x 4 x 4 = 64.
The little 3 tells how many fours to multiply together.
Now, can you tell me what 5² is?
