Place Value

Place Value:

We start with hundreds (100), tens (10), and ones (1).

For example, 273 = 2 hundreds + 7 tens + 3.

The right side is called expanded form. The left side is called standard form.

Example 1 : Express 98 in expanded form

98 = 9 tens + 8 ones

Example 2 : Express 1 hundred + 2 tens + 1 ones in standard form.

The standard form of this number is the digits in the expanded form : 121

Example 3 : Express 3 hundreds + 5 ones in standard form.

Here there are no tens, so we write it as 3 hundreds + 0 tens + 5 ones, which becomes 305.
