Question

The temperature at 5 p.m. was −4 ∘F. The temperature rose 7 ∘F once the sun came up at 8 a.m. the next morning.

What was the temperature at 8 a.m. that morning?

Answer 1

The temperature at 5:00pm was -4°F. The temperature rose (it means adding) 7°F once the sun came up at 8:00am.

Write an addition expression.

(-4)+(+7)

-4+7

+3

(The answer is positive because it matches the sign of 7, the numerically larger number)

Therefore, the temperature was 3°F.

Answer 2

3 degrees F

Explanation:

-4 + 7 = 3
