The document explains and provides examples of expanded form notation for numbers. Standard form notation writes a number as the sum of powers of ten, such as 250 = 200 + 50 + 0. Expanded form explicitly writes out the hundreds, tens, and ones place values added together, such as 250 = 200 + 40 + 10. The document provides the expanded form for several 3-digit numbers as examples.
