Answer
7
Work Step by Step
Use the order of operations to solve.
$3^2+12\div3-2\times3$ $\longrightarrow$ resolve exponent
$=9+12\div3-2\times3$ $\longrightarrow$ multiply/divide working left to right
$=9+4-2\times3$ $\longrightarrow$ multiply/divide working left to right
$=9+4-6$ $\longrightarrow$ add/subtract working left to right
$=13-6$ $\longrightarrow$ subtract
$=7$
