Did you try solving all four choices and seeing which one actually gives you 21.5?
OpenStudy (cookie_2046):
No do i do that?
terenzreignz (terenzreignz):
Easiest way to do it ^^
PEMDAS
Remember to do EVERYTHING inside parentheses first.
Then first perform the multiplications or divisions.
THEN finish off by doing the additions or subtractions.
First choice:
35 / 7 - (5 + 4)
First do the stuff in the parentheses...
35 / 7 - (9)
Next, do the division
5 - 9
Then finally, do the subtraction.
-4
And this isn't 21.5, so look at the other choices and see which one IS.

If you're not sure of yourself, why don't you try solving d? ^^
Nothing wrong with making sure :D
OpenStudy (cookie_2046):
I get 41
terenzreignz (terenzreignz):
haha, really, now? ^^
Show me your steps in how you managed to get that number. I bet you didn't do the stuff inside the parentheses first :P
OpenStudy (cookie_2046):
Wait that one is correct
terenzreignz (terenzreignz):
