It seems you're highlighting a pattern in the addition problem by pointing out how the digits in the ones place add up.
Indeed, when you add 22 and 17:
- The ones digits are 2 (from 22) and 7 (from 17), which together give 2 + 7 = 9.
- The tens digits are 2 (from 22) and 1 (from 17), which together give 2 + 1 = 3.
So, the sum of 22 + 17 = 39 can be understood as follows:
- The sum of the ones place (2 and 7) = 9.
- The sum of the tens place (2 and 1) = 3.
- Combining these gives you the final result, 39.
If you're looking for a specific conclusion or continuation to fill in the blank, you might say:
"notice that the 2 ones and the 7 ones make 9, and the 2 tens and the 1 ten make 3, leading to the total of 39."
