Reading and Writing Whole Numbers

Whole numbers are numbers such as:

1, 2, 3, 4, 5, 6…

Examples:

  • 1,245 = One thousand, two hundred and forty-five.
  • 3,610 = Three thousand, six hundred and ten.
  • 9,999 = Nine thousand, nine hundred and ninety-nine.

Place Value

In the number 4,582:

Digit Place Value
4 Thousands
5 Hundreds
8 Tens
2 Units

So:

4,582 = 4,000 + 500 + 80 + 2

This is called the expanded form.

Comparing Numbers

We use:

  • > means greater than.
  • < means less than.
  • = means equal to.

Examples:

5,400 > 3,200

2,150 < 2,500

4,000 = 4,000
