You are watching: The set of all whole numbers and their opposites
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.
5 Negative Integers Are to the left of zero.
Are valued less than zero. Can be expressed using words such as down, below or loss. The sign for a negative integer is (-). This sign is always needed.

7 Try this… Depositing Sinking Down Above Climb –up Withdraw Fell Positive Negative Positive Negative
8 Negative integers are valued less than zero, and are always to the left of zero. Zero is neither positive or negative Positive integers are valued more than zero, and are always to the right of zero.
14 The “net worth” of opposite integers is zero.
15 Opposite Integers Opposite integers always have a “net worth” of 0. This is called the ZERO PRINCIPAL. Opposite integer have the same “absolute value”, meaning the distance from the points on a number line to zero is the same. This can be referred to as the integers magnitude.
