Answer
- According to the order of arithmetic operations, calculate the division first：In an arithmetic expression without parentheses, when there is both division and addition/subtraction, division is calculated first. 75÷25=3, and the original expression becomes 3−1+2.
- Then calculate the addition and subtraction in sequence：Calculate from left to right. 3−1=2, 2+2=4.
So, 75÷25−1+2=4.
