Ib qho piv txwv ntawm cov cuab yeej sib txuas hauv lej yog dab tsi?
Cov cuab yeej sib txuas ntxiv: Hloov qhov kev txiav txim ntawm cov khoom ntxiv tsis hloov cov lej. Piv txwv li, 4 + 2=2 + 4 4 + 2=2 + 4 4 + 2=2 + 44, plus, 2, equals, 2, plus, 4. Associative property of plus: Hloov cov pab pawg ntawm addends tsis hloov. cov sum.
Ib qho piv txwv ntawm commutative khoom ntawm kev sib npaug yog dab tsi?
Cov cuab yeej cuab tam ntawm kev sib faib: Hloov qhov kev txiav txim ntawm yam tsis hloov cov khoom. Piv txwv li, 4 × 3=3 × 4 4 × 3=3 × 3 × 4 4 × 3=3 × 44, x, 3, sib npaug, 3, xuaj, 4.
Yuav ua li cas yog cov cuab yeej sib txuas hauv lej?
