Basis, an Uncommon card
In mathematics, a set B of elements of a vector space V is called a basis if every element of V can be written in a unique way as a finite linear combination of elements of B. The coefficients of this linear combination are referred to as components or coordinates of the vector with respect to B.

Basis quiz: 3 questions
Three questions on the Basis card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
This ______ deals mainly with finite-dimensional vector spaces.
Answer
article. This article deals mainly with finite-dimensional vector spaces. From the Basis article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Basis. Basis 72 · Axe 69 · Masonry 66 · Abha 63 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.
- Equivalently, a set B is a basis if its elements are linearly independent and every element of V is a linear combination of elements of B. In other words, a basis is a linearly independent spanning set.
- A vector space can have several bases, however all the bases have the same number of elements, called the dimension of the vector space.
- This article deals mainly with finite-dimensional vector spaces.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Basis article was read about 74,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 49: each hit it takes is cut by 20 %.
How to get Basis
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.
