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 | alfu | makumi ya maelfu |
| 1 | 4 | 3 | 2 | 7 | ||||||
| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . |
Weka sifuri katika mahali pa idadi tupu:
| Thamani ya mahali | makumi ya maelfu | alfu | mia | kumi | moja | . | kumi | mia | alfu | makumi ya maelfu |

2. Toa nambari kwa kutumia njia ndefu ya kutoa
Kwa sababu tarakimu ya juu (0) katika safu ya makumi ya maelfu ni ndogo sana kupata tofauti chanya, kukopa 1 kutoka kwa idadi ya kushoto (7.000) ambayo inakuwa (6.999) na kupata (10).
