Wait. So, in America, you get taught PEMDAS? I was taught BIDMAS, which means that the division/multiplication are in different orders on either side of the Atlantic.

Maybe it's to do with time differences?


Yep, in America, we are taught PEMDAS, which means multiplication comes before division. I'm pretty sure the solution will remain the same regardless, though.

Algebraically it's because the rational numbers form a commutative field. Division by x is just multiplication by the inverse of x (which exists for every x by definition of a field), and then the result follows from commutativity of multiplication in the rational numbers.

There's technically no such basic operation as "division". What we call "x/y" is in fact just the product "xy^-1", just like "x - y" is just the sum "x + (-y)".
