[quote=Anonymous][quote=Anonymous]I'm sorry, math teacher, but addition/subtraction and multiplication/division can be done right to left, left to right, it doesn't make any difference as long as the signs are in the right place. -10+5-9+6 is the same as 6-10-9+5 or any other order you want to put it. Same with 8*4/3 is 8/3*4... How much math does one actually have to study to become a math teacher? [/quote] Another math teacher here: although this is true, more people understand it if explained the other way as many students hesitate at bringing the signs with the numbers. Both are equally good explanations. Sometimes you need to Teach it a couple ways for people to get why. I agree that PEDMAS creates problems, as demonstrated by all the answers of 10.[/quote]
