412 + 563 = (400 + 10 + 2) + (500 + 60 + 3)

When we do subtraction, we subtract the ones from the ones, the tens from the tens and the hundreds from the hundreds.
679 – 325 = (600 + 70 + 9) – (300 + 20 + 5)
Let's write the sum in a different way: 679 – 325 354
When you subtract, you must ALWAYS subtract the ones ±rst, then the tens and the hundreds last.
