The set of integers consists of zero, the natural numbers and their additive inverses. This is often denoted by a boldface Z ("Z") standing for the German word Zahlen, "numbers".

Any symbol can be used to denote a set of integers. The set of all integers is denoted by Z, and the set of natural numbers by N.

Z, or more commonly denoted, ℤ (double line), is just the standard set mathematicians use to hold the set of all integers. Not everything stems from English, and in this case, the "Z" comes from the word "die Zahlen", which is the German plural word for numbers.

The symbol for the set of integers is Z. This comes from the German Zahl, which means integer.

Yes. Suppose x divides y then there exist an integer p such that y = px. Suppose y divides z then there exist an integer q such that z = qy. Therefore z = q*px = qp*x Since p and q are integers then pq is an integer and therefore x divides z. That is to say: if x divides y and y divides z, then x divides z.

It is Z from the German for "to count". The counting, or natural numbers are denoted by N.

It is the set of integers, denoted by Z.

There are no real reason why it is denoted by z, but that the real number axis is denoted by x, imaginary number is denoted by y, the real part of a complex number is denoted by a, the imaginary part of a complex number is denoted by b, so there is z left.

The set of integers, often is denoted by Z.

The blackboard bold style Z, used to indicate the set of integers, derives from the German word zahlen, meaning numbers.

An integer can be denotated by any letter. Teachers/professors may use different letters as a means to represent on a graph (i.e. x,y,z axis), but there is usually no real meaning behind why the letter 'z' was chosen over 'q'.

-10 belongs to the set of all integers denoted by Z.

Whole numbers are integers greater than or equal to zero.

Any symbol can be used to denote a set of integers. The set of all integers is denoted by Z, and the set of natural numbers by N.

To start with, the set of integers is a Group. This means that it is a set of elements (numbers) with a binary operation (addition) that combines any two elements in the set to form a third element. This Group, Z, satisfies four axioms: closure, associativity, identity and invertibility. that is, if x , y and z are integers, thenx + y is an integer (closure).(x + y) + z = x + (y + z) (associativity)there is an integer, denoted by 0, such that 0 + x = x + 0 = xthere is an integer, denoted by -x, such that x + (-x) = (-x) + x = 0.In addition, it is a Ring. A ring is an Abelian group (that is, addition is commutative: x + y = y + x) and it has a second binary operation (multiplication) that is defined on its elements. This second operation satisfies the axioms of closure, associativity and identity. It is also distributive over the first operation. That is,x*(y + z) = x*y + x*z
