Tropical geometry, an Uncommon card
In mathematics, tropical geometry is the study of polynomials and their geometric properties when addition is replaced with minimization and multiplication is replaced with ordinary addition: x ⊕ y = min { x, y }, x ⊗ y = x + y.

Tropical geometry quiz: 3 questions
Three questions on the Tropical geometry card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
So for example, the ______ polynomial x 3 + x y + y 4 would become min { x + x + x, x + y, y + y + y + y }.
Answer
classical. So for example, the classical polynomial x 3 + x y + y 4 would become min { x + x + x, x + y, y + y + y + y }. From the Tropical geometry article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Social theory. Social theory 73 · Tropical geometry 70 · Max Nordau 67 · Malathion 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.
- So for example, the classical polynomial x 3 + x y + y 4 would become min { x + x + x, x + y, y + y + y + y }.
- Such polynomials and their solutions have important applications in optimization problems, for example, the problem of optimizing departure times for a network of trains.
- Tropical geometry is a variant of algebraic geometry in which polynomial graphs resemble piecewise linear meshes, and in which numbers belong to the tropical semiring instead of a field.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Tropical geometry article was read about 37,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 46: each hit it takes is cut by 18 %.
How to get Tropical geometry
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.
