This is an altitude. Shown by the right angle on the side opposite the point.
Estimation for addition: 86 rounds up to 90 and 17 rounds up to 20 so:
90 + 20 = 110
Estimation for subtraction is the same thing but with subtraction
90 - 20 = 70
Now for the exact answers:

86 - 17 = 69
Your answers are 110, 70, 103, and 69.
