Maelezo kwa hatua
1. Andika tena nambari kutoka juu kwenda chini, zimepangwa kwa thamani zao za eneo
| Thamani ya mahali | makumi ya maelfu | alfu | mia | kumi | moja | . | kumi | mia |
| 5 | 4 | 0 | 0 | 0 | ||||
| - | 3 | 2 | 1 | 4 | . | 0 | 3 | |
| . |
Weka sifuri katika mahali pa idadi tupu:
| Thamani ya mahali | makumi ya maelfu | alfu | mia | kumi | moja | . | kumi | mia |
| 5 | 4 | 0 | 0 | 0 | . | 0 | 0 | |
| - | 3 | 2 | 1 | 4 | . | 0 | 3 | |
| . |
2. Toa nambari kwa kutumia njia ndefu ya kutoa
Kwa sababu tarakimu ya juu (0) katika safu ya mia ni ndogo sana kupata tofauti chanya, kukopa 1 kutoka kwa idadi ya kushoto (4000.0) ambayo inakuwa (3999.9) na kupata (10).
