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 | . | 8 | 1 | |||
| - | 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 |
| 1 | 4 | 3 | 2 | 7 | . | 8 | 1 | 0 | 0 | |
| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . |
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 (10) ambayo inakuwa (09) na kupata (10).
| Thamani ya mahali | makumi ya maelfu | alfu | mia | kumi | moja | . | kumi | mia | alfu | makumi ya maelfu |
| 0 | 9 | 10 | ||||||||
| 1 | 4 | 3 | 2 | 7 | . | 8 | 1 | 0 | 0 | |
| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . |
Toa nambari kwenye safu ya makumi ya maelfu kutoka kwa namba juu:
10-0-2=8
| Thamani ya mahali | makumi ya maelfu | alfu | mia | kumi | moja | . | kumi | mia | alfu | makumi ya maelfu |
| 0 | 9 | 10 | ||||||||

| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . | 8 |
Toa nambari kwenye safu ya alfu kutoka kwa namba juu:
9-8=1
| Thamani ya mahali | makumi ya maelfu | alfu | mia | kumi | moja | . | kumi | mia | alfu | makumi ya maelfu |

| - | 2 | . | 6 | 3 | 8 | 2 | ||||
| . | 1 | 8 |
Kwa sababu digit ya juu (0) katika safu ya mia ni ndogo sana kupata tofauti chanya, azima 1 kutoka kwa digit (8) katika nafasi inayofuata ya namba ambayo inakuwa (7) na kupata (10).

Toa nambari kwenye safu ya mia kutoka kwa namba juu:
