INTEGERS

Integers: 0, 1, -365, 1234567890, 989, 17                E

Not Integers: 0.5, -1002.9, 2/3, pi, surds

Rational and Irrational 

Rational numbers come in three forms:

1. Integers (4 = 4/1)

2. Fractions - where both numbers are non-zero integers

3.Terminating or recurring decimals (0.125 = 1/8)                        C 

Irrational numbers                                                                     

These are messy and cannot be written down as they are never-ending, non-repeating decimals
