Question

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

Answer 1

alright so this sounds like a trick question. If there was a decrease in 13 degrees over a certain period of time (7 hours) which resulted in a final temperature of -2. 13+(-2)= 11

Answer 2

13+ (-2) is the same thing as saying 13-2 which equals 11
