minus-square[email protected]Alinkfedilinkarrow-up2·1 year agoPEMDAS sucks as a mnemonic, we can agree on this. Try 8/2(2+2) on an actual calculator that’s used by scientists. Something like a Ti-83 would show 16, not 1.
minus-squareTWeaK@lemm.eelinkfedilinkEnglisharrow-up1arrow-down2·1 year agoReplace (2+2) with x: 8 / 2x = 4 / x = 4 / (2+2) = 1 Implicit multiplication takes priority over division. My Casio fx-991 gives 1. If I put in an explicit multiplication, then I get 16.
