Question

what is called variable ? Give one example.​

Answer 1

Answer:

A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

Answer 2

$\huge\bf\underline\pink{Answer࿐}$

A symbol for a value we don't know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the variable. ... In general it is much easier to always call it a variable even though in some cases it is a single value.
