You have \[(3 \times 6) + \left(\frac{12}{2}\right)  8\] Inside the first set of parentheses is $3 \times 6$ so perform the multiplication to get $18.$ Inside the second set of parentheses is $\large \frac{12}{2}$ so perform the division to get $6.$ hence you expression becomes \[(3 \times 6) + \left(\frac{12}{2}\right)  8 = 18 + 6  8.\] Finally $18 + 6  8 = 16.$ Penny
