Opposite Numbers & Additive Inverses Practice Problems & Conceptual Mastery
Find the opposite (additive inverse) of any positive or negative integer, evaluate double negative expressions -(-a) = a, and solve additive inverse zero-sum equations.
📝 Worked Step-by-Step Example
-7 is 7 units to the left of 0. Its opposite is 7 units to the right of 0, which is +7.
❓ Frequently Asked Questions
What is the difference between an opposite and an absolute value?
The opposite reverses the sign of a number (the opposite of 6 is -6, and the opposite of -6 is 6). The absolute value measures the non-negative distance from 0 (both |6| and |-6| equal 6).
What is the opposite of 0?
The opposite of 0 is 0. Because 0 has zero distance from itself, reflecting across 0 keeps it exactly at 0.
What does additive inverse mean in simple terms?
Additive inverse is the formal mathematical term for opposite. It is the number you must add to an original value to produce a sum of 0.
Why is the opposite of a negative number positive?
Negative numbers lie to the left of 0. Reflecting across 0 in the opposite direction moves you to the right of 0, where positive numbers are located.
