@IceWolf@masto.brightfur.net You just need to read the original poster's 6-post thread. It's all in there. The key observation is that left associativity is a fundamental property of division. You can in fact carry out the multiplication and division operations in any order you like, so long as you constrain yourself to left associativity. e.g. 18 ÷ 3 x 2 = 18 x 2 ÷ 3 That's guaranteed because order does not in fact matter, so long as we respect the constraint of left associativity, as we must because division demands it. PEMDAS simply gives us a simple mnemonic to ensure that we always do.
