• D. 8

Answer: (C)

To find the result of the calculation 9 - 4 + 2, one must follow the order of operations, which dictates that calculations be performed from left to right when there are only addition and subtraction involved.

First, start with the initial number: 9. Then, perform the subtraction of 4 from 9:

9 - 4 = 5

Next, take this result of 5 and add 2:

5 + 2 = 7

Thus, the final result of the calculation 9 - 4 + 2 is 7. It’s important to follow the sequence strictly to arrive at the correct solution. This step-by-step approach reinforces understanding of basic arithmetic operations, including how addition and subtraction interact within an expression.
