The facts on the card
The card carries these facts from its Wikipedia article.
- Linear algebra is central to almost all areas of mathematics.
- For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such as lines, planes and rotations.
- Also, functional analysis, a branch of mathematical analysis, may be viewed as the application of linear algebra to function spaces.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Linear algebra article was read about 240,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 51: each hit it takes is cut by 20 %.
How to get Linear algebra
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.
