Linear equation, an Uncommon card
In mathematics, a linear equation is an equation that may be put in the form a 1 x 1 + … + a n x n + b = 0, where x 1, …, x n are the variables, and b, a 1, …, a n are the coefficients, which are often real numbers.

Linear equation quiz: 3 questions
Three questions on the Linear equation card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
To yield a meaningful equation, the ______ a 1, …, a n are required to not all be zero.
Answer
coefficients. To yield a meaningful equation, the coefficients a 1, …, a n are required to not all be zero. From the Linear equation article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Murray S. Hoffman. Murray S. Hoffman 62 · Linear equation 59 · Antônio Muniz 50 · Anglo-American Freemasonry 46 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Linear equation. Linear equation 82,000 · Anglo-American Freemasonry 64,000 · Murray S. Hoffman 450 · 2012 LZ1 350 Wikipedia reads over a year.
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.
- The coefficients may be considered as parameters of the equation and may be arbitrary expressions, provided they do not contain any of the variables.
- To yield a meaningful equation, the coefficients a 1, …, a n are required to not all be zero.
- Alternatively, a linear equation can be obtained by equating to zero a linear polynomial over some field, from which the coefficients are taken.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Linear equation article was read about 82,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 59 and blocks with 33: each hit it takes is cut by 13 %.
How to get Linear equation
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.
