Question

Evaluate.

-8[(12-6)+3]+4
___________
9-2(2+3)

Answer 1

To solve, use pemdas. First, we'll start with the top,
`-8[(12-6)+3]+4`, subtract 12-6 as it's in parenthesis and inside the second pair of parenthesis,
`-8[(12-6)+3]+4=-8[6+3]+4`, now, add the 6 and 3 as they're in the last pair of parenthesis,
`-8[6+3]+4=-8[9]+4`, now multiply the -8 and 9 as they are touching via parenthesis, making them multiplied by each other,
`-8[9]+4=-72+4`, now add the 4 to -72,
`-72+4=-68`. Now, do the bottom.
`9-2(2+3)`, first add the 2 and 3,
`9-2(2+3)=9-2(5)`, then multiply the 2 and 5,
`9-2(5)=9-10`, now, subtract 9 and 10,
`9-10=-1`. Now, divide the top and bottom.
`(-68)/(-1) =68/1=68`.
