Question

what is the Variable?​

Answer 1

Answer:

$<font color =magenta>$

In mathematics, a variable is a symbol used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions. Making algebraic computations with variables as if they were explicit numbers allows one to solve a range of problems in a single computation. A typical example is the quadratic formula, which allows one to solve every quadratic equation by simply substituting the numeric values of the coefficients of the given equation for the variables that represent them.

Answer 2

Answer:

A variable is a named unit of data that may be assigned a value. If the value is modified, the name does not change. Some variables are mutable, meaning their values can change. ... If a variable's value must conform to a specific data type, it is called a typed variable.
