  • 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.
