You use PEMDAS, which is Parenthesis, Exponet, Divide, Multiply, Add, Subtract. You have to do it in that order.So 6x9+6x0.5 is a problem you have to use PEMDAS for.P&E go togehter, so when there is only parentesis or exponets, and no other symbols, then you do the problem across - left to right. Same with D&M, and A&S.In the problem 6x9+6x0.5, M (multiply) is the first symbol. So, 6x9 is 54, and 6x0.5 is 3. Then, A (add) comes next, and then no more symbols. So just add 54 to 3 and you get 57.The answer to 6x9+6x0.5 is 57, AKA - 6x9+6x0.5=57
72 but there is such a thing as a CALCULATOR
16 + 16 + 18 + 18 = 68
2x4
48or it could be 18 if it was 6x(9-6)

In the back where the 6x9's are housed there are the 6x9 covers simply pop them up with a screw driver. from there unscrew the screws all around remove the 6x9. keep in mind the 6x9 factory are clipped on simply cut the clippings strip the wire and connect them according to the new 6x9 you purchase
18 + 18 + 18 = 54
U = 4 x 18 U = 72
