Does it really? 4/2 = 2, 2 X 1 = 2. It's the same for me on my planet.

We learn CORLAT which translates as Parenetheses|Brackets, Indicies|Powers|Orders|Exponents, Division, Multiplication, Addition, Subtraction. But Div,Mult can be swapped as can Add,Sub.

I think the BIDMAS,BODMAS,PEDANT is a smokescreen. Unless you look at the second operator (indicies), there's very little that can go wrong.

CORLAT is another I've not heard of but it's the same order as BIDMAS so our results are the same.
