About these worksheets
Three-digit subtraction brings the algorithm’s hardest case into play: borrowing across a zero (503 − 267). The set mixes no-borrow, single-borrow and across-zero problems so the full skill gets exercised. Across-zero problems turn up at random: some sheets have one or two, others have none. No difference is ever negative, and each sheet’s answer key makes self-checking routine.
Need more sheets?
The generator makes new versions of this worksheet: choose the operation and the number of digits, and every click is a new sheet with its own answer key.
Frequently asked questions
Does it include borrowing across zeros?
Some sheets do — problems like 503 − 267 come up at random, so not every sheet has one. That case is the one worth the most practice; when it appears, have the child say each borrow out loud.
Are any answers negative?
No, the larger number is always on top.
