## Homework Statement

The following table shows the daily high tem-

peratures for a week in May. Determine the

change in temperature each day.

Sun. 76◦

Mon. 72◦

Tues. 80◦

Wed. 75◦

Thurs. 75◦

Fri. 74◦

Sat. 78◦

Find the net change in temperature (the

sum of all the temperature changes).

## Homework Equations

None

## The Attempt at a Solution

I know this seems easy, but I'm not getting the right answer:

Sun. to Mon. = -4 degrees

Mon to Tues. = 8 degrees

Tues. to Wed. = -5 degrees

Wed. to Thurs. = 0 degree

Thurs. to Fri. = -1 degree

Fri. to Sat. = 4 degrees

Sat. to Sun. = -2 degrees

Added them up and got: 0 degree

Am I suppose to just add up the absolute value of the temperature changes?
