Let’s check out your problem:

Omar tried to evaluate an expression. Here is his work:$\newline$$3 \times 2^3 \div 2 \times 4 - 1 + 2$$\newline$$3 \times 8 \div 2 \times 4 - 1 + 2$ {Step $1$}$\newline$$24 \div 2 \times 4 - 1 + 2$ {Step $2$}$\newline$$24 \div 8 - 1 + 2$ {Step $3$}$\newline$$3 - 1 + 2$ {Step $4$}$\newline$$2 + 2$ {Step $5$}$\newline$$4$ {Step $6$}$\newline$Is Omar's work correct?$\newline$(A)No, Omar made a mistake going from Step $2$ to Step $3$. Omar should have divided $24$ by $2$ before multiplying. The order of operations says to multiply and divide from left to right.$\newline$(B)No, Omar made a mistake going from Step $4$ to Step $5$. Omar should have added $1$ and $2$ before subtracting. The order of operations says to add before you subtract.$\newline$(C)Yes, Omar's work is correct.
