Question

Corey records the temperature in degrees Celsius each morning. At 8am the temperature was 3 degrees below zero. It rose 3 degrees by 10am. Which equation shows the change in temperature from 8am to 10am?

A 3+3=6
B-3+3=0
C-3+3= -6
D-3-3= -6​

Answer 1

B

It was 3 degrees below so the 3 will be a negative 3. Then by 10 it rose up by 3 so it is a positive 3. So -3+3=0
