-3+3=0 by adding. -3 and +3 If I say subtract -3 from 3 the answer is 6. Do you agree. Therefore I am saying pemdas is out dated. There's no subtraction in Pemdas. Division is another point of contention. I say change div to multiplication and invert. That get rid of d. Use PEMA. No confusion with left to right. Hope this makes maths easy
3+ 9 = 12 -3 + 3 = 12
