Algebraic number quiz: 3 questions
Three questions on the Algebraic number card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Algebraic numbers include all ______, rational numbers, and n-th roots of integers.
Answer
integers. Algebraic numbers include all integers, rational numbers, and n-th roots of integers. From the Algebraic number article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Algebraic number. Algebraic number 63 · Bicarbonate 60 · Tridax procumbens 57 · Ammonium acetate 53 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.
- For example, the golden ratio / 2 is an algebraic number, because it is a root of the polynomial x 2 − x − 1, i.e., a solution to the equation x 2 − x − 1 = 0, and the complex number 1 + i is algebraic because it is a root of the polynomial x 4 + 4.
- Algebraic numbers include all integers, rational numbers, and n-th roots of integers.
- Algebraic complex numbers are closed under addition, subtraction, multiplication and division, and hence form a field, denoted Q ¯.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Algebraic number article was read about 45,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 63 and blocks with 40: each hit it takes is cut by 16 %.
How to get Algebraic number
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.
