Question

When the chef turned the new freezer on, the temperature on the internal thermometer was 2 c .
After breakfast had been served the temperature had gone down by 15c.
What was the new temperature?

Answer 1

-13 c I think.  It is this way because if it went down 15, then you subtract 2-15.  2-2 = 0, and then 0-13= -13 c.  Hope this helps

Answer 2

The new temperature is -13°C.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Initial temperature(T1) = 2°C

Temperature change(ΔT) = -15°C

Final temperature(T2) = ?

ΔT = T2 - T1

T2 = T1 + ΔT

T2 = 2°C - 15°C

T2 = -13°C

Hence, the new temperature is -13°C.
