Txhais : Cov associative khoom hais tias koj tuaj yeem ntxiv lossis ntau Txawm hais tias cov lej raug muab faib li cas. Los ntawm 'pab pawg' peb txhais tau tias 'koj siv kab lus li cas'. Hauv lwm lo lus, yog tias koj ntxiv lossis kev sib npaug nws tsis muaj teeb meem qhov twg koj muab cov kab lus. Ntxiv ib co kab lus nyob qhov twg koj nyiam!.

Kev sib txuas lus vaj tse : Thaum ob tug lej yog multiplied ua ke, cov khoom yog cov tib yam tsis hais qhov kev txiav txim ntawm cov multiplicands.
Tsis tas li ntawd, dab tsi yog associative thiab commutative property?
Hauv lej, cov associative thiab commutative zog yog cov kev cai lij choj siv rau qhov sib ntxiv thiab sib npaug uas ib txwm muaj. Cov associative khoom hais tias koj tuaj yeem rov pab pawg lej thiab koj yuav tau txais cov lus teb tib yam thiab cov khoom vaj khoom tsev hais tias koj tuaj yeem txav tus lej nyob ib puag ncig thiab tseem tuaj txog ntawm tib lo lus teb.
