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 $=7$
