Stop, stop, stop. You're going to fill someone's brain with false information. Besides, you're doing it wrong. Once the calculations inside the brackets/parentheses are completed, then multiplication and division are done in order from left to right. Thus:
8 / 2(2+2)
8 / 2(4) which becomes
8 ÷ 2 × 4
4 × 4
16
Taken from @JakkFrost's comment and paraphrased to be like Hermione Granger's "Stop, stop, stop. You're going to poke someone's eye out. Besides, you're doing it wrong. It's 'Leviosa,' not 'LeviosAaAr.'"
