Question

1. A Football team gained 4 yards on a play, lost 8 yards on the next play, then gained 2 yards on the third play. Write an addition expression to describe the total change of yardage. Then determine the sum and explain its meaning

Answer 1

We have been given that the football team gained 4 yards on a play, lost 8 yards on the next play, then gained 2 yards on the third play.

Gain can be represented by plus and loss can be represented by minus sign.

Thus, we have

gained 4 yards means +4

lost 8 yards means -8

gained 2 yards means +2

Therefore, the addition expression to describe the total change of yardage is given by

$+4-8+2$

Now we have

$+4-8=-4$

Thus, we have

$-4+2\\ =-2$

We got minus sign, which means loss.

Hence, the football team lost 2 yards.
