I know it goes
You. follow that formula
But calculator say it's 5
I did addition before subtraction, like bedmas, is formed; the only way I get 5 is to subtract before adding.
Then why don't we call it Bedmsa if subtraction comes first?
Actually, why even have a word for it if it doesn't even matter?
If you taught it as PEDMSA it would still be wrong. Your error is that you worked the equation from right to left. The issue happens at 4-3+4, which is actually 5 because you treat subtraction and addition as the same order, and work them from left to right. The acronym should actually be taught as PE (MD)(AS), illustrating that in the order of operations you first deal with parenthesis, exponents then (multiplication and division) then (addition and subtraction). The second rule being you treat addition and subtraction with the same priority and work them from left to right.
Why did we even make an Acronym anyways if it just confuses :P
I see it called Order of Operations but school has never called it that before every time I heard it was Bedmas and nothing more I just learned the real name today
Yeah, it's an order of operations acronym. Doesn't have anything to do with associative properties.
