Question

What operation should be performed first in the expression [23 × (4 + 3)] ÷ 9 - 1?

Answer 1

remember pemdas...you should do whatever is in parenthesis first

here you have

[23 x (4 + 3)]

so you would do the INNERMOST parenthesis first (4+3)
Then do the remaining what is left in those brackets.....23 x (...)

Then continue on
