An exponent is a number that tells how many times the base number is
used as a factor. For example, 3^{2} indicates that the base number 3
is used as a factor 2 times. To determine the value of 3^{2}, multiply
3*3 which would give the result 9.

Squares indicate that the exponent has a value of two. The term square comes
from the geometrical shape that has the same width and length. To find the area
of a square you would multiply the width times the length.

Exponents are written as a superscript number (e.g. 3^{2}) or preceded
by the caret (^) symbol (e.g. 3^2).

Some facts about exponents:

- Zero squared is zero (e.g. 0
^{2} = 0)
- One squared is one (e.g. 1
^{2} = 1)
