Find the sum. Hint: add the ones and then add the tens. 52 add 17.
The question asks us to find the sum. The sum is the total you get when you add together two or more numbers.
The hint tells us we should first add the ones and then of the tens. Let’s add the ones first. Two plus seven equals nine. And then we have to add the tens. The sum of 52 and 17 is 69.
