Could you rewrite PEMDAS as PEMADS and it still be the same order of operations? Why or why not?

No, you cannot switch A (addition) and D (division). Division must always happen before addition.

Could you rewrite PEMDAS as PEDMAS and it would still be the same order of operations? Why or why not?

Yes because M (multiplication) and D (division) happen in the same step.
