Answer:
33 degrees
Step-by-step explanation:
It is 21 degrees inside the command center and negative 12 degrees outside.
You want to find the difference between these, which means you want to subtract.
That will look like:
21 - (-12) = ?
since you have two negative signs next to each other, they will cancel each other out.
Our new equation:
21 + 12 =
21 + 12 = 33
The difference between these two temperatures is 33 degrees.
