\((10*4+2)(9+6 / 3)\)         (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
