Scalar multiplication quiz: 3 questions
Three questions on the Scalar multiplication card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Scalar multiplication is the multiplication of a vector by a scalar, and is to be ______ from inner product of two vectors.
Answer
distinguished. Scalar multiplication is the multiplication of a vector by a scalar, and is to be distinguished from inner product of two vectors. From the Scalar multiplication article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Flight management system. Flight management system 59 · Scalar multiplication 53 · Armor-piercing bullet 50 · Reflection nebula 46 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.
- In common geometrical contexts, scalar multiplication of a real Euclidean vector by a positive real number multiplies the magnitude of the vector without changing its direction.
- Scalar multiplication is the multiplication of a vector by a scalar, and is to be distinguished from inner product of two vectors.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Scalar multiplication article was read about 20,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 53 and blocks with 25: each hit it takes is cut by 10 %.
How to get Scalar multiplication
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.
