how?
3+2 = 5
Because of Piano's Axiom!
This should help: 3 - (-2) = 3 -1*(-2) -1*(-2) = 2, so 3-(-2) = 3+2 = 5

3 + 2 means the second succession of 3 which is 5.
Because of the rule when two negative sign are next to each other it becomes positive/plus sign: -- = + -+ = - ++ = +
Cheers guys. @ opiesche thumbs up!!

yes because two negatives make a positive
