Ukuba amagama athi ""amanani a-natural"" ""natural numbers"" ngesiNgesi, akasetyenziswa, kuyakweza ukubhideka ekubeni ingaba u-0 uyabandakanyeka na okanye hai. Kodwa ngelishwa, abanye abantu bathi u-O akalonani lipheleleyo (akayo-whole number, ngesiNgesi), bakwathi abanye amanani apheleleyo (iiwhole numbers) zisenokuba negative. ""ii-Positive integers"" nee-""non-negative integers"" ziyenye indlela yokubandakanya okanye yokukhuphela ngaphandle u-zero, kodwa oko kungenzeka kuphela xa abantu bewazi loo magama.
