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. ^_^

I'm kinda stuck on this one, but i think it's d? i may be wrong

terenzreignz (terenzreignz):

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):
