The third problem is: +70 - 14 = 56

Solution:

This is a subtraction problem. We subtract 14 from 70. In the ones place, 0 - 4 requires borrowing. So, we borrow 1 from the tens place (7 becomes 6) and add 10 to the ones place (0 becomes 10). Then, 10 - 4 = 6. In the tens place, 6 - 1 = 5. Combining these gives us 56.
