Why is math so hard -

it goes right

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer

using the formula for pythagorean theorem (a2+b2=c2)(the twos are exponents), and knowing that you have b squared and c squared, just reverse it. 26 squared minus 10 squared equals c squared. 26 squared is 676 and 10 squared is 100. you get 576, then use your square roots to undo the squared numbers to get 24.

if p is true and q is false, then p ∨ q is true
