Division by zero quiz: 3 questions
Three questions on the Division by zero card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
That is, c = a b is ______ to c × b = a .
Answer
equivalent. That is, c = a b is equivalent to c × b = a . From the Division by zero article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Dynamic programming. Dynamic programming 79 · Division by zero 74 · Goldbach's conjecture 71 · Aerospace engineering 68 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- Using fraction notation, the general example can be written as a 0 , where a is the dividend.
- The usual definition of the quotient in elementary arithmetic is the number which yields the dividend when multiplied by the divisor.
- That is, c = a b is equivalent to c × b = a .
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Division by zero article was read about 140,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 60: each hit it takes is cut by 24 %.
How to get Division by zero
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
