Ppl use () so they can see the difference between negative values and minus. But if you are talking about values like

2x-3⁴ = only -3 get the power of 4
(2x - 3)⁴ = 2x and -3 get the power of 4
90 - because you take 30 + 30 = 60 then you multiply it by .5 to ad the 50% more, then you add that to the original 60 to get the price of the more expensive book. you can check you work by adding them together 30+30+90=150.
