OT: Order of Arithmetic calculations

AnthonyL · 2025-07-11T12:39:31+00:00

I came acrossFor those who don't do Farcebook it shows a Casio fx-991ex and aSmartphone calculating the formula:6/2((1+2) (actually the divide symbol -:- which I can't do with oldFree Agent)The Casio gives the result as 1The Smartphone gives the result as 9So I checked my Smartphone which gave 9 as did both Libre Calc andExcel =6/2*(1+2). From what I learnt at school (and I did AdvanceMaths a looong time ago even though this is arithmetic) and would saythe answer is 1.So when did the sequence change from left to right rather thanmultiplication has precedence over division?
