What temperature is 15 degrees lower than seven degrees Celsius and how would you work it out

Answer 1

The question is asking us to find the temperature which  is 15 degrees lower than seven degrees Celsius.

The mathematical symbol used for lower than is a subtraction sign that is -.

15 lower than 7 degree = 7-15 = -8.

7 and 15 have opposite sign so will  be subtracted .The answer will take the sign of the bigger number.

The  temperature that  is 15 degrees lower than seven degrees Celsius is -8°C

Answer 2

To figure this out, subtract 15 from 7 and you get –8. So your answer is -8˚ C.
