Best comment i have seen today: Assume that leap years begin in year 0 (they don’t, but it’s a good benchmark) 2001 is the year Half Life came out for PlayStation. 495 leap years since year 0 (not including 0) (2001/4 = 500 R1 (drop R); 2000/400 = 5, 500 -5 = 495) (every four hundred years a leap year is not counted) 4 + 9 + 5 = 18 Make it a complex trinomial (3 terms; see where I’m going with this?), drop 18 for now so the discriminant formula can be used easily 4x^2 + 9x +5 = 0 Using the discriminant formula : b^2 – 4ac 9^2 – 4(4)(5) 81 – 80 = 1 D > 0 Therefore there are two real roots Using the quadratic formula: X = -1.25, x = -1 SUM OF ROOTS: -2.25 -2.25 x -1 (root) = 2.25 Bring back 18 from 4 + 9 + 5 18 / 2.25 = 8 5 leap years knocked off (400, 800, 1200, 1600, 2000; remember 0 is not counted) 8 – 5 is 3. Half Life 3 Confirmed.
