    Hapa ni baadhi ya mali muhimu ya kutofautiana:

    Mali ya Usawa

    Ikiwa\(a\),\(b\), na\(c\) ni namba halisi, basi:

    Mpito Mali kama\(a < b\) na\(b < c\) kisha\(a < c\)

    Aidha Mali kama\(a < b\) basi\(a + c < b + c\)

    Ondoa Mali kama\(a < b\) basi\(a − c < b − c\)

    Mali ya kuzidisha (Kuongezeka kwa idadi nzuri) ikiwa\(a < b\) na\(c > 0\) kisha\(ac < bc\)

    Mali ya kuzidisha (Kuongezeka kwa idadi hasi) ikiwa\(a < b\) na\(c < 0\) kisha\(ac > bc\)

    Idara ya Mali (Kugawanya kwa idadi chanya) kama\(a < b\) na\(c > 0\) kisha\(\dfrac{a}{c} < \dfrac{b}{c}\)

    Idara ya Mali (Kugawanyika kwa idadi hasi) kama\(a < b\) na\(c < 0\) kisha\(\dfrac{a}{c} > \dfrac{b}{c}\)

    Hakuna mifano au kazi za nyumbani katika sehemu hii.
