Understand the problem

3+33×232= 3+\frac{3}{3}\times\frac{2}{3}-2=

2

Step-by-step solution

According to the rules of the order of arithmetic operations, we first place the multiplication exercise inside of parentheses:

3+(33×23)2= 3+(\frac{3}{3}\times\frac{2}{3})-2=

We then solve the exercise in the parentheses, combining the multiplication into a single exercise:

(33×23)=3×23×3=69=23 (\frac{3}{3}\times\frac{2}{3})=\frac{3\times2}{3\times3}=\frac{6}{9}=\frac{2}{3}

We obtain the following exercise:

3+232= 3+\frac{2}{3}-2=

Lastly we solve the exercise from left to right:

3+23=323 3+\frac{2}{3}=3\frac{2}{3}

3232=123 3\frac{2}{3}-2=1\frac{2}{3}

Final Answer

123 1\frac{2}{3}
