    the "dot" should mean "times" :) (unless it's a decimal LOL) So we want to solve the following: \[\frac{ 9 \times 3 - 3 \times 5 }{ 4} = ?\]

    corrrect! So if we plug that into our equation we have this: \[\frac{ 9 \times 3 - 3 \times 5 }{ 4 }\] \[= \frac{ 27 - 15 }{ 4 }\] Now, we want to simplify this. What does 27 - 15 = ?

    excellent! :D So now we have \[\frac{ 12 }{ 4 } = ?\] 12 divided by 4 equals to?
