The convention I understand with regard to a modulo operation is that they are of equal importance when following the rules of PEDMAS. Yet when I ask wolfram alpha something like 7*7 modulo 8/10 it does the multiplication and division before doing the modulo operation. Is it not supposed to be left to right in calculation even when no brackets are used? Is this an order of operations bug?
I would always use brackets to separate statements like that.
