>>12252487>why does MDAS exist in PEMDASIt really doesn't. It's something that American schools came up with, but in some of them it's PEDMAS. I imagine that PEDMSA and PEMDSA and the likes could also exists. You're just used to the most popular one. People who can into math understand that the only thing that matters is the precedence of the operator:
>first powers>second products>third sumsRoots are fractional exponents, division is a fractional product, and subtractions are negative sums, so they all have the same precedent as the integer version. Solve things from left to right when precedence is the same and no problem can ever be ambiguous.
