Subtraction Worksheet Generator

Printable worksheets of twenty subtractions written in columns, with two-digit, three-digit or four-digit numbers, with or without borrowing. Every worksheet also has its answer key, with the digits that borrowing rewrites and the differences.

Column subtraction works like column addition, from right to left, starting with the ones. When a digit on top is smaller than the digit under it, you borrow: you take one ten from the next column, which makes the top digit 10 more. The worksheets without borrowing let beginners learn the layout first; the ones with borrowing practice the step that needs the most care. You can check each answer by adding it to the number you subtracted: you should get the top number back.

Every worksheet has twenty different subtractions, written in columns. Without borrowing, each digit on top is at least the digit under it; with borrowing, every subtraction needs at least one borrow. The page is made in your browser: nothing is sent to Zuzuzi, and it is free, with no sign-up.
