Topic Detailed Information
Expanded form writes a number as the sum of each digit multiplied by its place value. It helps students see how a large number is built.
For example, 62,739 = 60,000 + 2,000 + 700 + 30 + 9. Zero places are usually skipped in expanded form, but students should still mark them in the place value chart.
Expanded form improves reading, comparing, and rounding numbers because each digit position becomes clear.
