OpenStudy (anonymous):

Explain how to solve \[8^ 2 + 9(12 ÷ 3 • 2) – 7\]

OpenStudy (supercait10):

haha funny i'm am doing tenth grade math and have no clue what to do for number 9

OpenStudy (anonymous):

a) do what is inside the parentheses first divide and multiply in order form left to right

pooja195 (pooja195):

@satellite73 would we use PEMDAS?

pooja195 (pooja195):

*wouldnt

OpenStudy (anonymous):

inside the parentheses is \(12\div3\times 2\)

OpenStudy (anonymous):

pemdas is a lazy math teachers mnemonic device it doesn't mean anything

OpenStudy (supercait10):

i got it my older sister's best friend helped me

OpenStudy (anonymous):

besides, this is a good example of where, if taken literally, you would get the WRONG answer

OpenStudy (anonymous):

OpenStudy (supercait10):

138 and she is in 11th grade taken collage math

pooja195 (pooja195):

LOL go for xD its wrong

OpenStudy (supercait10):

all my teacher is going to do is take off half of a point due to i'm three weeks ahead of school work

OpenStudy (anonymous):

trouble is math is not really based on trust @pooja195 will you quit doing that??

OpenStudy (anonymous):

you want to do it the correct way?

pooja195 (pooja195):

Nope and 12/3=4 right? so... 64+9(4)(2)−7 =64+(9)(8)−7 =64+72−7 =136−7 = ?

OpenStudy (supercait10):

i'm already a 100% she is only going to knock out me down to 99%

pooja195 (pooja195):

You do what you want then.

OpenStudy (supercait10):

pooja195 (pooja195):

OpenStudy (supercait10):
