The Zero Property of Opposites
The Zero Property of Opposites is a Grade 7 math skill from enVision, Mathematics, Grade 7, covering Integers and Rational Numbers. The sum of an integer and its opposite is always zero. Explanation An integer and its opposite are the same distance from on a number line, but in opposite directions. When you add an integer and its opposite, they cancel each other out, resulting in a value of zero. For example: Examples * The numbers and form a zero pair because their sum is .
Key Concepts
The sum of an integer and its opposite is always zero. For any integer $a$: $$a + ( a) = 0$$.
