positive integer m.Lloyd is bored one day,so makes a list of the value of n − Z(n!)for each integer n from 100 to 10 000,inclusive.How many integers appear in his listat least three times?\5\5\5\5\5(Note:If n is a positive integer,the symbol n!(read “n factorial”) ...
In mathematical notation, it is often represented by the symbol ∀ (for all). For example, the statement "For all real numbers x, x + 1 > x" asserts that no matter the value of x, adding 1 to it will always result in a value greater than x. 2. Universal Quantification: Similar...
就是x的次方，2的40幂就是 2的40次方
A null set, also known as an empty set, is a set that has no elements. This is denoted by the symbol { }. For example, the set of all prime numbers greater than 10 is a null set because there are no prime numbers greater than 10. ...

A symbol may stand in for say the radius of a circle over its diameter. But the real number that is represents cannot be expressed with exact precision. Sets have their limits. Set theory also breaks down on this simple idea: Take the set that includes all sets that do not contain ...
Each face of these dice features the first eight digits of pi arranged in a circle around the pi symbol. Each of the numbers 1-6 is contained in the first eight digits of pi, and one of them is enlarged on each face, allowing the dice to be used like regular d6 dice. Single die...
Two integers a and b are said to be relatively prime, mutually prime, or coprime if the only positive integer that divides both of them is 1. Any prime number that divides one does not divide the other. This is equivalent to their greatest common divisor (gcd) being 1. (See Tutorial:...
