Why are the numbers -2 and 2 called "zero pairs?" Use the number line below to illustrate your
1 answer:
The numbers -2 and 2 are zero pairs as they <u>add up to zero</u>.
Zero pairs as coming from the name, zero implies a zero, and pair implies a couple. A zero pair is a pair of numbers that sums up to zero.
In the question, we are asked why are the numbers -2 and 2 called zero pairs.
The given pair of numbers, -2 and 2, when added up, that is, (-2) + 2, gives the result as 0, that is,
(-2) + 2 = 0.
Thus, pair 2 and -2 is called zero pair.
Using a number line, we know for adding, we move towards the right.
When at -2, on adding two, that is, moving two units right, we reach 0, proving that -2 and 2 are a zero pair.
