Ho lumeloa hore ho ne ho le joalo Archimedes ea hlahisitseng mekhoa ea pele e lebisitseng mohopolong oa mongolo oa mahlale.

Thelinomoro ho notation ea mahlale li ngotsoe e le sehlahisoa sa palo e felletseng kapa ea decimal pakeng tsa 1 le 10 le matla a base 10.

Ka tsela ena, notation ea mahlale e arabela foromong e latelang: n x 10^x o n x 10^-x. Joalo ka ts'ebetso e sebetsang, ho ka boleloa hore ho fetolela lipalo tse kholo ho feta 1 ho notation ea mahlale, o tlameha ho beha sekhahla kamora nomoro ea pele ebe o bala sehlahisoa ho latela hore na ho setse libaka tse kae ka letsohong le letšehali.

Ho fetolela lipalo tse ka tlase ho 1 ho notation ea mahlale, U tlameha ho beha sekhahla kamora motsotsoana oa bobeli ho isa ho oa ho qetela ebe u bala sehlahisoa ho latela hore na ke libaka tse kae tse ka ho le letona tse setseng, e hlalositsoeng e le mpe. Mehlala e fanoeng kaholimo, nomoro ea Avogadro e ne e tla ba 6.022 × 10²³ boima ba haedrojene ke 1.66 × 10^-23.

Linomoro ho notation ea mahlale le tsona li ka ngoloa joalo ka mongolo o hlalosang mantsoe. Mohlala, 4 × 10⁸ e ka ngoloa e le 4e + 8.

Ho atisa lipalo ho notation ea mahlale, u tlameha ho atisa dinomoro ka lehlakoreng le letshehadi, sehlahisoa seo se atisoa ka tse 10 se phahamisitsoeng ho fihlela kakaretso ea li-exponents tse ling. Ho arola lipalo ho notation ea mahlale, o tlameha ho arola linomoro tse ka lehlakoreng le letšehali, sephetho seo se atisoa ke 10 se phahamisitsoeng ho tlosa bahlahlobi.
