About this worksheet
Twenty mental math problems that take hundreds or tens away from a three-digit number, like 650 - 200 and 874 - 30. The hint at the top says only one digit should change, which turns each problem into a quick place value check.
A couple of problems, like 990 - 90 and 600 - 500, are worth pausing on, because the answers look surprising until you see which digit moved. It builds directly on the take away 10 and 100 sheet.
