Air temperature -3 ° C. How many degrees will the thermometer show if the air temperature changes

Air temperature -3 ° C. How many degrees will the thermometer show if the air temperature changes: 1) by + 5 ° C 2) by -4 ° C

First, let’s carry out the calculations of the first part of the problem statement. It is known that initially the air temperature was -3 ° С, and then it changed by + 5 ° С. In order to determine which mark the thermometer will show, you need to perform such calculations

(-3) + (+5) = -3 +5 = + 2 ° C.

Let us perform the calculations for the second condition in a similar way, but in this case the temperature changed by -4 ° С. Therefore, the result will be like this

(-3) + (-4) = -3 – 4 = -7 ° C.

This means that in the first version the thermometer will show + 2 ° С, and in the second – -7 ° С.
