The temperature on February 2 in Lake City was 14°F. The temperature in Ellenville the
same day was -6°F. How much warmer was it in Lake City than in Ellenville?
To solve the problem, Gabby subtracted 14 - (-6) and came up with an answer of 8°F. Is
Gabby correct? Why or why not?
Yes, Gabby is correct.
No. The answer should have been 20°F, not 8°F, because subtracting a
negative number is the same as adding its opposite.
No. Gabby should have added -6 + 14 because the temperature in Lake City
was warmer.
