(12−6+9)×(7+3)= (12-6+9)\times(7+3)= (12−6+9)×(7+3)= ?
According to the order of operations, we will first solve the expressions in parentheses and then multiply:(12−6+9)=(6+9)=15 (12-6+9)=(6+9)=15 (12−6+9)=(6+9)=15
(7+3)=10 (7+3)=10 (7+3)=10Then solve the multiplication exercise:15×10=150 15\times10=150 15×10=150
150 150 150
