Without numbers, mathematics can not exist. There are a variety of numbers which you are required to know about.

Real Numbers
These are rational and irrational numbers.
Rational Numbers
These will always have terminating or recurring decimals. This means they can always be turned into a fraction.
Irrational Numbers
These can not be turned into a fraction. They are non-terminating.
Integers
These are whole positive or negative numbers (-3, -2, -1, 0, 1, 2, 3).
Prime Numbers
These are numbers with only TWO factors, itself and 1.
Square Numbers
These numbers are formed by a number multiplied by itself (1, 4, 9, 16...).
