In these lessons, we will learn how to write numbers in expanded form, standard form and word form.

### Expanded Form

Numbers can be written in expanded form. Expanded form can be demonstrated in two ways.

For example:
4123 = 4,000 + 100 + 20 + 3
or
4123 = (4 × 1,000) + (1 × 100) + (2 × 10) + (3 × 1).

50,302 = 50000 + 300 + 2
or
50,302 = (5 × 10,000) + (3 × 100) + (2 × 1).
