Correct Answer
A. -1Explanation
The expression (-7) + 8 - 6 - (-4) can be simplified by first removing the parentheses. The negative sign in front of (-4) can be rewritten as a positive sign, resulting in (-7) + 8 - 6 + 4. Then, we can combine like terms by adding and subtracting from left to right. Starting with (-7) + 8, we get 1. Then, subtracting 6 from 1 gives us -5. Finally, adding 4 to -5 gives us -1. Therefore, the correct answer is -1.Rate this question:

Correct Answer
A. -18Explanation
The given expression involves multiplication and addition/subtraction. According to the order of operations (PEMDAS/BODMAS), multiplication is performed before addition/subtraction. So, we first multiply 2 and -3, which gives us -6. Then, we add -5 and -6, which gives us -11. Finally, we subtract 7 from -11, resulting in -18. Therefore, the correct answer is -18.Rate this question:
