Method 1: Royalty
Brackets (Castle)
Multiply/ Divide (King & Queen)
Plus/Minus (Prince & Princess)
=> Left to Right
We need to solve those in the Castle first. For the equation in the bracket, the king/queen followed by prince/princess rule still follows.
And it's always left to right rule if both (only king and queen) or (only prince and princess) are in the equation.
