Two-Digit Subtraction Practice

Practice two-digit subtraction in vertical format with numbers from 10 to 99 — a natural mix of problems that need borrowing (regrouping) and problems that don't, with answers that never go negative.
Borrowing is where subtraction gets its reputation. The mechanical rule ("borrow one from the tens") only sticks when students understand they are trading one ten for ten ones — and quick, repeated practice with instant feedback is how the trade becomes routine.
Tips That Make It Stick
- Check the ones column first. If the top ones digit is smaller than the bottom one (as in 52 − 38), a borrow is coming. Spotting it early prevents mid-problem confusion.
- Add back to verify. After computing 74 − 29 = 45, check that 45 + 29 returns 74. Addition is subtraction's built-in answer key.
- Trade, don't "cross out". Say "trade one ten for ten ones" instead of "cross out the 7". Language that describes the place-value trade builds real understanding.
Frequently Asked Questions
What is borrowing in subtraction?
When the top digit in a column is smaller than the bottom digit, one unit is traded from the next column — one ten becomes ten ones. In 52 − 38, the 2 becomes 12 and the 5 tens become 4.
Why does my child make more mistakes in subtraction than addition?
Subtraction with borrowing has more steps and an order requirement — and unlike addition, it is not commutative. Short daily practice with immediate feedback fixes far more than longer weekly sessions.
Can I practice without borrowing first?
Yes — after loading the game, open game settings and set regrouping to "none" for borrow-free problems, then switch to "required" when ready to focus on borrowing.
