Hello!
The difference means to subtract we would get what is seen below.
14--25
Subtracting means to do the opposite of something, so subtract 25 instead of adding it. When you have two subtraction signs in means to do the opposite of the opposite. As you can see it cancels out and it stays the same. If you subtract a negative number, you actually add its positive integer.
14+25
39
The difference is 39 degrees.
I hope this helps!
