3-Digit Subtraction with Regrouping Worksheets

Three-digit minus three-digit subtraction where every problem borrows at least once — from the tens, from the hundreds, or both, and sometimes across a zero (for example 405 − 178), the case that trips most children. Twenty problems to a page with the answer key on page 2.

Questions

Does it include borrowing across zero?

Yes, whenever the random numbers produce it (a 0 in the tens of the top number with a borrow needed from the ones). It is not forced on every problem.
