In mathematics, a number is any discrete or continuous value. Discrete values are used for counting and ordering to determine unity or multitude among separate entities and for showing position in a series. Continuous values are used for measuring to determine magnitude along a given range. Numbers are used non-mathematically for labeling persons, places, and things. Numbers can be expressed symbolically by digits, words, or in the case of algebra, letters.
It is not defined in mathematics since if allowed, it would lead to contradictions.
In mathematics, an irrational number is any real number which cannot be expressed as a fraction a/b, where a and b are integers, with b non-zero, and is therefore not a rational number
In mathematics, a field is a set on which addition, subtraction, multiplication, and division are defined and behave as the corresponding operations on rational and real numbers do. A field is thus a fundamental algebraic structure which is widely used in algebra, number theory, and many other areas of mathematics.
Not all linear functions have defined slope. In two dimension it is definet but in three dimensions it cant be defined; For that direction ratios are defined in mathematics.
Certainly, infinity can be defined. It can't be perfectlydefined, but then, as Wittgenstein demonstrated some time ago, there are really no perfect definitions of anything. All language is approximate, even in mathematics (which is more precisely defined than most subjects). Infinity is defined as an endless quantity, greater than any number that can be counted.
A variable in Mathematics is defined as the alphabetic character that expresses a numerical value

In mathematics, an operation is a function which takes zero or more input values to a well-defined output value. The number of operands is the arity of the operation.
Geometry is a branch of mathematics that deals with the position, size, and shape of figures.
