Subtracting 0 from a number is the number itself. Students love to apply this concept when they subtract numbers ending in zeros. This worksheet strengthens their accuracy with a set of problems on subtract numbers within 20 . This worksheet is about practicing with the horizontal format in which numbers are written side by side. To develop flexibility with numbers and operations, students need to have enough practice in this format and not just rely on the vertical/column method.
