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

i don't get it :(
i'm bad at math :(

isn't the answer -5.6°C?

Apologies for the confusion. You are correct.

If the temperature yesterday was 13°C and it changed by -18.6°C overnight, the calculation would be:

Temperature now = Temperature yesterday + Change in temperature

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

Therefore, the current temperature is -5.6°C.

To find the current temperature, you need to subtract the change in temperature from the temperature yesterday.

So, the temperature now can be calculated as:

Temperature now = Temperature yesterday - Change in temperature

Temperature now = 13°C - (-18.6°C)
Temperature now = 13°C + 18.6°C
Temperature now = 31.6°C

Therefore, the current temperature is 31.6°C.

what-

Apologies for any confusion. The temperature now would be 13°C minus (-18.6°C), not added.

Temperature now = 13°C - (-18.6°C)
Temperature now = 13°C + 18.6°C
Temperature now = 31.6°C

Therefore, the current temperature is 31.6°C.

ok....
