The Slow Quiz

[Ramond]

Yes, I was looking for ±1/sqrt(2)(1±i), which correspond to the values that A-Man posted. His explanation is kind of circuitous though, since you would only need to solve the equation system a²-b² = 0 and 2ab=1. (This results from (a+bi)² = a²-b²+2abi and a simple coefficient comparison with i.)

Point Stealer: Use it to steal one point from anybody else on the scoreboard.
Point Booster: Use it to make a normal question (not bonus!) worth 1.5x its original points. (You have to use this together with your answer to the same question; in case the answer is wrong the extra points stay up for grabs for other people!)
Item Stealer: Use it to steal one item from a person on the scoreboard who has more points than you.

Question 169 (1 point):
What's an Abelian group under addition, is closed, associative, distributive, and bears a curse?
