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.

##### Mifano Template:index
 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)

##### Zoezi Template:index

Kwa mazoezi yafuatayo kulinganisha namba zifuatazo na kujaza tupu kwa kutumia ishara sahihi$$<$$,$$>$$,$$\geq$$,$$\leq$$ au$$=$$

1. $$−1\underline{\qquad} 4$$
2. $$−4\underline{\qquad} 9$$
3. $$0\underline{\qquad} −2$$
4. $$3\underline{\qquad} 3$$
5. $$−12\underline{\qquad} 12$$
6. $$4\underline{\qquad} 6$$
7. $$−1\underline{\qquad} -1$$
8. $$5\underline{\qquad} −2$$
