On February 18, from 9 a.m. until 2 p.m., the temperature rose from -14(degrees)F to 38(degrees)F. What was the total increase in temperature during this time period?

Guessing didn't work on this problem.

14 + 38 = 52 degrees

24-i guess

To find the total increase in temperature during this time period, we need to subtract the initial temperature from the final temperature.

The initial temperature is given as -14°F, and the final temperature is given as 38°F.

To find the total increase, we subtract the initial temperature from the final temperature:
38°F - (-14°F)

To subtract a negative number, we change the subtraction operation to addition and change the sign of the number being subtracted:
38°F + 14°F

Adding these numbers together, we get:
38°F + 14°F = 52°F

Therefore, the total increase in temperature during this time period is 52°F.
