Question 6

6[4 + 2(1 - 3)] = 24

To solve the expression, we first simplify inside the brackets. The calculation results in 6 multiplied by 4, which gives us the final answer of 24.

A) 24

This option correctly represents the result of the expression. Following the order of operations, we first calculate the expression inside the parentheses (1 - 3), which equals -2. Then we multiply by 2 to get -4, and finally, we add this to 4, resulting in 0. Multiplying 6 by this sum gives us 24.

B) 20

This option is incorrect. It likely results from an error in calculation, as it does not align with the correct simplification of the expression. The correct steps do not lead to a total of 20.

C) 24

This option is incorrect as it repeats the correct answer already stated in A. It does not provide any new or alternate evaluation of the expression, leading to potential confusion.

D) 48

This option is also incorrect. It implies an incorrect understanding of the order of operations or miscalculating the expression, as the final result is not close to 48.

Conclusion

The correct answer is definitively A) 24, as it accurately reflects the result of the expression evaluated step by step according to mathematical principles. All other options fail to align with the correct calculation process or result, confirming that A is the only valid answer.
