Math: Integers – Comparing & Adding Overview

We are learning to compare integers

Principle 1: Any negative integer (-) is always less than any positive integer (+) E.g., (-1) < (+1)
Principle 2: A positive integer (+) closer to zero (0) is always less than a positive integer (+) farther away from zero (0) E.g., (+3) < (+12)
Principle 3: A negative integer (-) closer to zero (0) is always greater than a negative integer (-) farther away from zero (0) E.g., (-2) > (-5)

Zero Principle When you have the same number of negatives as positives, the result is zero (0).

(-1) + (+1) = 0

(-4) + (+4) = 0

We are learning to add integers

Principle 1: The sum of two negatives is negative.   
Principle 2 The sum of two positives (+) is positive. 
Principle 3: The sum of a (-) and a (+) will take the sign of the number that is farther from zero (0).
