3 Integers Integers are the set of all whole numbers and their opposites. Integers can either be negative(- ), positive(+) or zero. The integer zero is neutral. It is neither positive nor negative, but is an integer. Integers can be represented on a number line, which can help us understand the valve of the integer.

4 Positive Integers Are to the right of zero. Are valued greater than zero. Can be expressed using words such as up, gain or profit. The sign for a positive integer is (+), however the sign is not always needed. Meaning +3 is the same value as 3.
