Basic math inogona kukubatsira iwe muWebhu yekutsvaga kutsvaga. Heino nzira iyo inoshanda:
- Icho chisingaenzaniswi:
Shandisa "-" chiratidzo kana iwe uchida injini yekutsvaga kuwana mapeji ane izwi rimwe rekutsvaga kwavari, asi unoda injini yekutsvaga kuti usabvisa mamwe mazwi anowanzobatanidzwa neshoko iroro rekutsvaga. Semuyenzaniso:
- Superman -Krypton
Iwe uri kuudza injini dzekutsvaga dzaunoda kuwana mapeji anongova nemashoko okuti "Superman", asi usabvisa mazita ayo anosanganisira mashoko pamusoro pe "Krypton". Iyi inzira inokurumidza uye yakajeka yokubvisa ruzivo rwekare uye kuderedza kutsvaga kwako pasi; pamwe chete unogona kuita tambo yemashoko asina kubviswa, akadai: superman -krypton - "lex luthor".
