Answer:
- Calculate the multiplication according to the order of arithmetic operations: In arithmetic operations, multiplication and division are calculated first, followed by addition and subtraction. So first calculate 10×0=0, and the original expression becomes 50+0+7+2.
- Calculate the addition in sequence: Add in order from left to right. 50+0=50, 50+7=57, 57+2=59.
So, 50+10×0+7+2=59.
