How many stickers does Amy have left?

  1. 1

    Subtract the tens first

    • Start by subtracting the tens54 − 20 = 34
  2. 2

    Subtract the ones (bridging through 10)

    • Split 7 into 4 + 3, then subtract 4 to reach 3034 − 4 = 30
    • Then subtract the remaining 330 − 3 = 27

Amy has 27 stickers left.

The key insight: Break the subtraction into friendly steps - subtract tens first, then ones!

Common mix-up: 54 − 27 = 33 (swapping digits: 7 − 4 = 3). You must subtract the bottom digit FROM the top digit, not the other way round.
