Hello!

We know that from midnight to 6am the temperature went up 8° and at 6am it was -21°

To find what it was at midnight we have to work backwards

Since it went up we have to subtract 8 from -21

-21 - 8 = -29

The answer is -29°C

Hope this helps!

The answer would be -29C. If you have a negative number and i ROSE, or added, the negative number would change to a number closer to zero. So -21+8=-29
