Need to make a Touhou Math game where Cirno is the EX boss. From all the art I see it seems that if she had a calculator to do the arithmetic, she would be as good as any Math or Physics PHD.
There's actually an error in the diagram. It claims that the yellow part is the union of A and B, when in fact it's only the symmetric difference. The union would be the yellow part plus the red part.
Set - part 1Cirno's Perfect Math ClassHow many people are good and have one wife?
Answer is 7.How many people are good and have many wives?
Answer is 36.Is a multiple of 4 but not of 7.
Ans: 22"a" is a member of set "A".
A is contained in B.
(= B contains A.)"Sets A and B are equal" (It implies "A ⊂ B" and "A ⊃ B")IntersectionUnionThe set that contains all elements of A that also belong to B.Complement of AEmpty setThe set having no elements.The chart below is called a Venn diagram.The square's interior is a universal set.The red part isThe yellow part isThis blue part.The green part.Among the integers of 1 to 100 inclusive, find the number of integers in the following.Is a multiple of both 4 and 7.
Ans:3CardinalityIf we calculate by n(A)+n(B), those in both A and B will be counted twice.Refer to the graph.n(P) indicates the number of elements in a finite set P.
For following examples, A and B are finite sets.Φ has no element = has 0 elements.Neither a multiple of 4 or 7.
Ans:64* A set is a collection of distinct objects. Each object that makes up the set is called an element or member of the set.If a "universe set" U is defined, the collection of elements in U, but not in A.ExerciseWe asked 100 people whether you are "good or bad" at playing Touhou, and whether you have "one wife or more". The survey showed 43 are "good", 29 are "one wife", and 35 are "bad and more wives".Let universal set U={integers from 1 to 10 inclusive} have subsets A and B so that A∩B={3,6,8}, A'∩B'={4,5,7}, A∩B'={1,10}
Find sets A, B, and A∪B.
Ans: A={1,3,6,8,10} B={2,3,6,8,9} A∪B={1,2,3,6,8,9,10}The collection of elements which are in A or in B.
The Greek letter "Φ" In fact, this symbol is not related to the Greek letter.De Morgan's lawsEither a multiple of 4 or 7.
Ans:36Let U be the universal set of integers from 1 to 1000 inclusive.
If subsets A={multiples of 3}, B={multiples of 5}, find n(A'∩B').
Ans:533
