2-digit subtraction worksheets

Column subtraction with borrowing, constrained so no difference ever goes negative — print, practice, mark from the key.

Borrowing is the first place subtraction gets genuinely hard, and the only fix is volume with feedback. These sheets keep the difficulty honest — operands span the full two-digit range, so borrows appear on some lines and not others.

The separate answer-key page means whoever marks the sheet is not redoing the arithmetic — and the student cannot peek mid-sheet.

Sheet #1000. The same settings and number always produce the same sheet, so you can reprint an identical paper — or press New sheet for fresh problems at the same difficulty.

Questions

Do these include borrowing (regrouping)?
Yes, on the lines where the digits demand it. The mix of borrow and no-borrow problems is what shows whether the method is applied or memorized.
Can I make an easier version?
Drop the digits control to 1 for fact-level differences, or switch the operation to addition — the generator under this page does both.
