The correct answer is 3 degrees.
-7 + 10 Ten degrees higher (+10) than minus seven degrees (-7)
3 When adding a positive to a negative, the answer will be the difference between the two numbers. Whether the answer is positive or negative depends on which number is larger; for instance, in this case, 3 is positive because 10 is larger than 7.
Therefore, the answer is 3 degrees.
Hope this helps!
