Obu buchule benzululwazi kunye neentsomi zezibalo ngumahluko omangalisayo kwaye uyolisa kakhulu oye wanomtsalane kwabafundi iminyaka engaphezu kwe-100.

Ichaza uhambo lwesikwere, ingcali yemathematics kunye nokuhlala kumhlaba othe tyaba ombini, apho abafazi, bethe tye, imigca ethe tye, iphantsi imilo, kwaye apho amadoda anokufumana naliphi na inani lamacala, kuxhomekeka kwinqanaba labo lentlalontle.
Ngeziganeko ezingaqhelekanga ezimnxibelelanisa neqela leefom zejometri, isikwere sine-adventure kumhlaba osendaweni (imilinganiselo emithathu), umgca womhlaba (umda omnye) kunye nendawo yomhlaba (akukho mida) kwaye ekugqibeleni inokonwabisa iingcinga zokutyelela umhlaba wabane Ubungakanani-umbono oza kubuyiselwa kuwo kwilizwe elinemilinganiselo emibini. Ibali alisiyomdla wokufunda nje kuphela, sisimangatye sentsingiselo yentsingiselo yokuqala yomxholo wobubanzi beendawo. "Iyafundisa, iyonwabisa, kwaye ivuselela umbono."
