Parentheses first lets do 10 + 4 * 8; Using order of operations, you know we do multiplication before addition so 4*8 = 32, now you can do 32+10 to get 42. Now the equation is 3{5 + 3(42)}, Now remember you do multiplication before addition so you distribute the 3 to the 42 to get 126. The new equation is 3(5+126) Now remember do the parentheses first, 126 + 5 = 131. Now distribute the 3; 3(131) = 393
Answer: 393 :)
