Mstari wa nambari ni kulinganisha namba. Hapa ni alama zinazotumiwa wakati wa kulinganisha namba mbili au zaidi:
| Alama kutumika | Soma kama |
| \(<\) | chini ya |
| \(\leq\) | chini ya au sawa na |
| \(>\) | kubwa kuliko |
| \(\geq\) | zaidi basi au sawa na |
| \(=\) | sawa |
Tahadhari:\(\leq\) na\(\geq\) hutumiwa kama namba zinazolinganishwa zinatimiza angalau moja ya masharti mawili.
Kumbuka: Kuhamia zaidi upande wa kushoto wa asili, namba zinapungua kwa thamani. Kuhamia zaidi kwa haki ya asili, idadi zinaongezeka kwa thamani.
| Taarifa | Sababu |
| \(−3 < −2\) | Tangu -3 ni zaidi ya kushoto ya -2 |
| \(5 > 1\) | Tangu 5 ni zaidi ya haki ya 1 |
| \(2 > −6\) | Tangu 2 ni zaidi na haki ya -6 |
| \(3 \geq 3\) | 3 si kubwa kuliko 3, lakini ni sawa! |
Kidokezo: Ishara\(>\) inaelezea mwelekeo sahihi. Nambari katika mwelekeo sahihi zinaongezeka hivyo tumia alama hii wakati namba ya kwanza ni kubwa kuliko namba ya pili. Fikiria vile vile kwa chini ya. (\(<\)akizungumzia kushoto hivyo chini ya)
Kwa mazoezi yafuatayo kulinganisha namba zifuatazo na kujaza tupu kwa kutumia ishara sahihi\(<\),\(>\),\(\geq\),\(\leq\) au\(=\)
- \(−1\underline{\qquad} 4\)
- \(−4\underline{\qquad} 9\)
- \(0\underline{\qquad} −2\)
- \(3\underline{\qquad} 3\)
- \(−12\underline{\qquad} 12\)
- \(4\underline{\qquad} 6\)
- \(−1\underline{\qquad} -1\)
- \(5\underline{\qquad} −2\)
- \(35\underline{\qquad} 53\)
- \(−29\underline{\qquad} −37\)
