Video Summary

To determine how many different sums Stephen can obtain from numbers on the board, we calculate all possible sums from the pairs of numbers. The smallest result comes from adding the two smallest numbers, 1 and 2, equaling 3, while the largest result comes from the two largest numbers, 4 and 5, equaling 9. All whole numbers between 3 and 9 can be obtained through various combinations: 3 from 1+2, 4 from 1+3, 5 from 2+3, 6 from 2+4, 7 from 2+5, and 8 from 3+5. There are seven different sums, hence the answer is C, 7.
