Question

The temperature outside dropped 13 degrees farenhiet in 7 hours. the final temperature was -2 degrees farenhiet. what was the starting temperature?

Answer 1

13 + (-2) = 15

Explanation:

13 is greater because the absolute value (13) is greater than the absolute value of -2 (2)

Which is why it is a negative answer, you need to add to get to the temperature it was before it dropped. Because both numbers are negative you just need to add to solve it.

Which is 15

Answer 2

Just count up from negative two to thirteen. Your answer is 15 degrees.
