Suppose you have a coupon for $5 off, followed by a 25% discount. You would use PEMDAS to evaluate .75(x - 5) (parentheses followed by multiplication).
I am a tournament Scrabble player, so I would use PEMDAS while keeping score. Suppose I play QUIXOTE (as a bingo) on a triple word with Q being doubled. Then my score for the word would be
3(2(10) + 1 + 1 + 8 + 1 + 1 + 1) + 50
Use the order of operations here:
= 3(33) + 50 = 149 points.
