Cov Additive Tus kheej Axiom hais tias tus lej ntxiv rau xoom sib npaug ntawm tus lej ntawd. Lub Multipplication Tus kheej Axiom hais tias tus lej sib npaug los ntawm 1 yog tus lej ntawd. Cov Additive Rov qab Axiom hais tias cov lej ntawm tus lej thiab cov Additive Rov qab ntawm tus lej ntawd yog xoom.

Tom qab ntawd, dab tsi yog qhov khoom sib txawv?

Peb siv inverse zog daws qhov sib npaug. Inverse Property ntawm Ntxiv hais tias txhua tus lej ntxiv rau nws qhov kev tawm tsam yuav sib npaug zero. Inverse Property of Multiplication hais tias txhua tus lej sib npaug los ntawm nws qhov sib npaug yog sib npaug rau ib qho.

Tsis tas li ntawd, dab tsi yog qhov hloov pauv ntawm kev ntxiv? Cov Inverse ntawm Ntxiv yog rho tawm Ntxiv txav peb ib txoj kev, rho tawm txav peb txoj kev opposite. Piv txwv li: 20 + 9 = 29 tuaj yeem thim rov qab los ntawm 29 − 9 = 20 (rov qab rau qhov peb pib)

Yog li ntawd, dab tsi yog ib qho piv txwv ntawm cov cuab yeej inverse?

Cov inverse khoom ntawm kev sib faib hais tias qhov khoom ntawm ib tus lej thiab nws qhov kev sib raug zoo yog ib txwm 1. Txhawm rau nrhiav qhov sib npaug ntawm tus lej, qhia tus lej no ua ib feem thiab tig cov feem. Rau piv txwv , qhov sib txuam ntawm 4 yuav yog 14. Piv txwv 1 −7×−17=?

Dab tsi yog inverse khoom ntawm kev rho tawm?

Plaub qhov kev ua lej tseem ceeb yog ntxiv, rho tawm , multiplication, division. Cov thim rov qab ntawm ntxiv yog rho tawm thiab vice versa. Cov thim rov qab kev sib faib yog division thiab vice versa.
