One of the Basic Math Rules You Learned In School Is Wrong
- rbkillea 13y agoI may be the only one who learned it this way, but here goes: Square Brace (BPEMDAS with a silent B) Parenthesis Exponent Multiply & Divide Addition & Subtraction When I learned PEMDAS (a long time ago) this was hammered into my head so well that I know the nuances to this day. In fact from what I recall there was 1 PEMDAS unit per year for a couple years in a row. Also, I hate sensationalism.
- claudius 13y agoThe problem is to prioritise addition over subtraction and multiplication over division rather than assigning them equal priorities and evaluating the expression left-to-right. In German, there is no ‘PEMDAS’ but only ‘Punkt vor Strich’ (‘Dots before dashes’?), i.e. multiplication/division (·,:) before addition/subtraction (+,-). Parentheses obviously still take precedence.
- cahitonur 13y agoI must be lucky then or my teacher was a real good one. I even didn't learn something like PEMDAS.
