Find the sum. Hint: add the ones then the tens. What do you do if you have more than 10 ones?

First, we need to add the ones, seven plus five: seven, eight, nine, 10, 11, 12. We can write the two in the ones column, and we need to carry the 10 across to the tens column. Now when we add in the tens column, we need to add four and one, which makes five. 45 add seven is 52.
