Answer：
- According to the order of arithmetic operations, calculate multiplication and division first：
- Division: 90÷9=10.
- Multiplication: 10×10=100.
At this point, the original expression becomes 90−100+10.
- Then calculate addition and subtraction：Calculate from left to right. 90−100=−10, −10+10=0.
So, 90−90÷9×10+10=0.
