For the example below , I have used brackets to get.. 18(4/3) = 72/3 Which is incorrect in the example solution.
In general, when should i use brackets?
How do I know when to use brackets and not to use it?
Is it because i have to multply it identically as the opposite side of the equations(did not use brackets)?
