Past the thousands column
250 bricks in one row, 40 rows high. That is 250 × 40 = 10,000 bricks. That is 10 times one thousand!
Step 1 of 4
- Start at one thousand.
- ×10 more — ten thousand.
- ×10 more — one lakh.
- ×100 more — one crore.
The rule
A column is a place in a number, like tens. Ten of one column make one of the next column. Ten lots of 10,000 make one lakh. Ten lots of 10 lakh make one crore.
| Column | Written | Made from |
|---|---|---|
| Thousands | 1,000 | 10 × 100 |
| Ten thousands | 10,000 | 10 × 1,000 |
| Lakhs | 1,00,000 | 10 × 10,000 |
| Ten lakhs | 10,00,000 | 10 × 1,00,000 |
| Crores | 1,00,00,000 | 10 × 10,00,000 |
Two shortcuts help. One lakh is a hundred thousand. 100 × 1,000 = 1,00,000. One crore is a hundred lakh. 100 × 1,00,000 = 1,00,00,000.
