After the 1990 census, Texas gained 3 seats in the United States House of Representatives. Michigan lost 2 seats. You can use the integers +3 and -2 to describe these situations, respectively.

13. Opposites All opposites add to zero. -3 + 3 = 0 (21) + (-21) = 0
Two numbers are opposites of one another if they are represented by points that are the same distance from 0, but on opposite sides of 0.
All opposites add to zero.
= (21) + (-21) = 0
