Answer
According to the order of arithmetic operations, calculate the multiplication first：In an arithmetic expression without parentheses, when there is both multiplication and addition/subtraction, multiplication is calculated first. 3×4=12, and the original expression becomes 13−12+2.
Then calculate the addition and subtraction in sequence：Calculate from left to right. 13−12=1, 1+2=3.
So, 13−3×4+2=3.
