# Whole number place value review

Review whole number place value, and try some practice problems.

## Place value chart

The number $\mathrm{7,654,321}$ can be placed on a place value chart as follows:

Millions | Hundred thousands | Ten thousands | Thousands | Hundreds | Tens | Ones |
---|---|---|---|---|---|---|

## Whole number place value

In a whole number, the digit farthest to the right is always in the ones place. The next farthest to the right is in the tens place. The remaining digits continue to fill in the place values until there are no digits left.

**Example:**$459$

The number ${4}{5}{9}$ is made up of ${4}$ hundreds, ${5}$ tens, and ${9}$ ones.

We can also write this as: ${4}{5}{9}={400}+{50}+{9}$ .

Or we can use a place value chart:

Thousands | Hundreds | Tens | Ones |
---|---|---|---|

**Note:**The farther the digit is to the left, the greater its place value. For example,
