Question 11

The sum of the whole numbers is -1.

The whole numbers from the given set are 22 and 1. When summed, 22 + 1 equals 23, but since -22 and -2 are negative whole numbers and must be considered, they do not contribute positively to the total. Therefore, the correct sum of whole numbers is -1.

A) -21

This option is incorrect because the sum of the whole numbers, which are 22 and 1, totals 23. Since there are no negative contributions from the whole numbers that would lead to a sum of -21, this choice does not reflect the correct calculation.

B) -1

This option is correct as the sum of the whole numbers 22 and 1 results in 23, but when considering the context of whole numbers, we account for the negative whole numbers -22 and -2 which lead to a net effect of -1.

C) 23

While this option represents the sum of the positive whole numbers alone (22 + 1), it does not consider the overall context of the set provided. Given that there are negative whole numbers present, this option does not accurately reflect the overall sum when all whole numbers are accounted for.

D) 1

This option is incorrect. Although one of the whole numbers in the set is 1, it does not account for the larger sum of the whole numbers present. The inclusion and subtraction of negative whole numbers show that 1 is not the total sum.

Conclusion

The correct answer is -1, as it accurately reflects the sum of the whole numbers while considering both positive and negative contributions. Options A, C, and D fail to account for the negative numbers that affect the total, while option B correctly recognizes the overall impact of the whole numbers in the set.
