Integers and Zero Pairs

Which addition equation matches the problem modeled ? (Yellow is positive, and red is negative)

• -2 + -4 = -6

• 2+ -4 = -2

• 4 + 2 = 6

What is the definition of a zero pair?

• Two negative numbers added together

• When you add zero and zero together

• A pair of numbers whose sum is zero

• Two positive numbers added together

• -7 + 4 = -3

• 7 + (-4) = 3

• 7 - 4 = 11

• 7 + (-4) = -11
