Multiplicative inverse, an Uncommon card
In mathematics, a multiplicative inverse or reciprocal for a nonzero number x, denoted by 1 x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1.

The facts on the card
The card carries these facts from its Wikipedia article.
- The multiplicative inverse of a fraction a b is b a. Dividing 1 by a real number yields its multiplicative inverse.
- For example, the reciprocal of 5 is one fifth, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
- The reciprocal function, the function f that maps x to 1 x, is one of the simplest examples of a function which is its own inverse function.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Multiplicative inverse article was read about 62,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 33: each hit it takes is cut by 13 %.
How to get Multiplicative inverse
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.
