Question

Devan checked the thermometer outside his window before going to bed. The temperature was 3F. During the night, he woke up and saw that the temperature had dropped 17 degrees. At noon, Devan noticed that the temperature had risen 21 degrees. What was the temperature at noon?

Answer 1

If the temperature starts at 3 and drops 17 during the night, then the temperature would be -14 degrees at night because 3 - 17 = -14. Then, if it increases 21 degrees to noon, the final temperature would be -14 + 21, which is the same as 21 - 14.
