Jije alòdì tabi àìlòdì je ohun ini nomba kan to je gidi, tabi ara omoakojopo awon nomba gidi bi awon nomba onipin ati odidi. Nomba alodi ni awon nomba tiwonkere ju òdo lo fun apere -${\displaystyle {\sqrt {2}}}$, -1.44, -1. Nomba adaju (fun apere nomba gidi todaju, nomba onipin todaju, nomba odidi todaju) je nomba topoju odo lo, fun apere ${\displaystyle {\sqrt {2}}}$, 1.44, 1. Òdo fun ra re ki se odi tabi odaju. Àwon nomba ailoodi je awon nomba adaju ati odo. Awon nomba aidaju je nomba alodi ati odo.
