solve the following problem

it was 13.C yesterday but the temperature changed by -18.6 overnight what is the temperature now

To find the temperature now, we need to subtract the change in temperature (-18.6) from the initial temperature (13.0).

Temperature now = Initial temperature + Change in temperature
Temperature now = 13.0 + (-18.6)
Temperature now = -5.6

So, the temperature now is -5.6 degrees Celsius.

To solve the problem, we need to find the temperature after the change.

The initial temperature was 13°C.

We have a decrease in temperature of -18.6°C overnight.

To find the temperature now, we need to subtract -18.6 from 13:

13 - (-18.6) = 13 + 18.6 = 31.6

Therefore, the temperature now is 31.6°C.
