Astmed
Ühe ja sama alusega astmete korrutamisel astendatakse alus antud astendajate summaga.
Valem: am ⋅ an = am+n
Näide: 125 ⋅ 129 = 125+9 = 1214
Ühe ja sama alusega astmete jagamisel astendatakse alus astendajate vahega.
Valem: am : an = am-n
Näide: 3625 : 3620 = 3625-20 = 365
Iga nullist erineva arvu astmes 0 on võrdne ühega.
Valem: a0 = 1, kus a≠0
Näide: 15230 = 1
