Kupiwa kwezita

"Tafura yaPythagoras"

Panoitwa Tafura yeKuwanza Huwandu, (multiplication table) sezviri pamufananidzo uri pamusoro, kune nhamba inoverengwa nayo inonzi mberengi, n. Kuruboshwe kwetafura zvichidzika ndiko kune mberengi, pamusoro petafura kubva kuruboshwe zvichienda kurudyi ndipo panoverengwa kuwanzwa kwemberengi.

• Kana mberengi yadanwa kamwe, zvakafanana nokuti n x 1.

• Kana mberengi yapamha kudanwa kagumi izvi zvakafanana nokuti n x 10 zvichingodaro.

• Kana mberengi yapamha kudanwa kechi makumi maviri, zvakafanana nokuti n x 20.

• Zvakafanira tiwonesane kuti pana n x 20, kana makumi maviri iriyo mberengi n ndiko kuverengwa kwekuti mberengi yadanwa kechingani. Saka nhamba dzose dziri mbiri dzinogonha kuva mberengi.
