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
