Best ResponseYou've already chosen the best response.0So if subtraction comes first instead of the addition you do it ?

Best ResponseYou've already chosen the best response.2It doesn't matter which order you do addition and subtraction since they are actually the same function (subtraction is like adding a negative number). In your equation above, you can do the addition step first, though note you are adding 9 to 14, not 14. You will get the same answer. Side note: similarly, multiplication and division are similar functions since division is like multiplying by a reciprocal.

Best ResponseYou've already chosen the best response.0but bedmas b=() e=exponents d=division m=multiplication a=addition s=subtraction so in pedmas what does the p stand for

Best ResponseYou've already chosen the best response.2BEDMAS and PEMDAS are exactly the same thing (B = brackets, P = parentheses). They rearrange the letters a bit to make fancy acronyms, but it doesn't make a difference. D and M can be performed in any order, and A and S can be performed in any order because, as I mentioned above, they are essentially the same operation.
