On one night in london the temperature fell to -12 on the same night in moscow the temperature fell to -5 what was the difference in temperature

So you start out with a temperature. The key word in the next part means to drop or decrease, and the word is fell. So you know we are talking about subtraction, since in subtraction you are taking away things, you are decreasing. Then it tells you another temperature, and that it fell -5 degrees, so you know definitely know this is subtraction we are talking about. So you set up the problem as this:

-12-(-5)= x.

The variable x in this case represents the difference in temperature that we don't know yet, or at least haven't figured out yet.

When you subtract two negatives with their signs like this -(-), you know to turn it into a plus. So basically, -12+5= -7!

Hope this helps, have a good day. c;
