a) we want two numbers where the difference of them is equal to 29. Where the difference between the numbers a and b is = a - b

You can use brute force here, this is, try for every option and find the correct one.

-45 - (-21) = - 45 + 21 = - 24, that pair is not the correct option

-45 - (-16) = - 45 + 16 = - 29, well, here we find that the difference between these two numbers is 29 units, so the correct option here is - 45 and - 16.

b) The summ of all the numbers in the list is:

S = - 45 + (-21) + (-16) + 12 + 33 + 40 = 3

So the total sum of the numbers in the list is 3
