We have created a chart that lists the numbers of zeros in a million, billion, trillions, and more In the following table, the first column lists the name of the number, the second gives the number of zeros that follow the initial digit, and the third shows you how many groups of three zeros you would need to write each number.

| Ten | 1 | (10) |
| Hundred | 2 | (100) |
| Thousand | 3 | 1 (1,000) |

| Hundred thousand | 5 | (100,000) |
| Million | 6 | 2 (1,000,000) |
| Billion | 9 | 3 (1,000,000,000) |
