Evaluate. (10 • 4 2)(9 6 ÷ 3)

Answers

$(10*4+2)(9+6 / 3)$ (first do the mutiplication and division)

$(40+2)(9+2)$ (add)

$(42)(11)$ (multiply)

$42 *11$

$462 \ \textless \ -answer$

first you multiply 10 and 4 because multiplication before addition and you get 40 then you add 40 and 2 to get 42 now you move to the second equation and you divide 6 and 8 because division comes before addition and you get 2 when you divide 6 and 3 now you add 9 and 2 and get 11 now you multiply 42 and 11 (because the parenthesis have nothing between them it means multiplication) and you get 462 as your answer
