Six Ways of Writing Whole Numbers
Number forms are the different ways of writing whole numbers. See below the six different ways of writing the same whole number.
The following table shows the number forms for a number much bigger than 324. Notice that in the figure above, we do not have a short word form for 324. However, we do have a short word form for the number 645927.
The short word form is used for numbers greater than one thousand.
| Number Forms | Example |
| Standard form | 645,927 |
| Word form or written form | six hundred fourty-five thousand, nine hundred twenty-seven |
| Short word form | 645 thousand, 927 |
| Expanded form | (6 × 100,000) + (4 × 10,000) + (5 × 1000) + (9 × 100) + (2 × 10) + (7 × 1) |
| Exponential form | (6 × 105) + (4 × 104) + (5 × 103) + (9 × 102) + (2 × 101) + (7 ×100) |
| Scientific form | 6.45927 × 105 |
