Answer 2

It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?

Answer 3

To find the temperature now, we need to subtract the change in temperature from the original temperature.

Original temperature: 13°C
Change in temperature: -18.6°

Temperature now = 13°C + (-18.6°)
Temperature now = -5.6°C

The temperature now is -5.6°C.
