$(16-4)\div2+3$
The order of operations states that first we perform operations inside grouping symbols, such as parentheses, brackets, and fraction bars. Then, we simplify powers. Then, we multiply and divide from left to right. Finally, we add and subtract from left to right. When we put parentheses around the $16-4$, it makes us subtract these terms first. This leaves us with $12\div2+3$ We then divide: $6+3$ Finally, we add, giving us $9$ and making the equation true.
