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

- supercait10

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

- anonymous

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

- pooja195

@satellite73 would we use PEMDAS?

- pooja195

*wouldnt

- anonymous

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

- anonymous

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

- pooja195

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