Tips for faster subtraction
Adjust ranges to practice borrowing and multi-digit subtraction.
- Use counting-up for tricky problems (e.g., 1000 - 647: count up 647->1000).
- Subtract in chunks: subtract hundreds, then tens, then ones.
- Use compensation: 83 - 29 -> 83 - 30 + 1.
- Common mistake: sign confusion (subtracting the wrong direction).
- Common mistake: borrowing errors on multi-digit subtraction.
- If you're slow, narrow the ranges until accuracy is automatic.
- Try accuracy sets: go slower but aim for zero mistakes for 2 minutes.
- Then do speed sets: 10-20 questions and race the clock.

Subtraction Practice FAQ
Yes - the generator swaps numbers so you won't get negative results for subtraction.
Increase the ranges so you frequently cross tens/hundreds boundaries (e.g., 40-200).
Use chunking and compensation, and practice daily with short focused sets.
