In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.
a variable
It can be any letter of any alphabet: Roman, Greek.
In mathematics, the symbol "X" typically represents an unknown variable. Therefore, "XX1X" could be interpreted as a mathematical expression with variables. Without further context or specific instructions, it is difficult to determine a precise meaning for this sequence of symbols. It is possible that it could represent a polynomial, an algebraic expression, or a placeholder for a specific value in a mathematical equation.
In an equation "x" is the value assigned to one of the unknown quantities in the equation. (example: y= mx+b). X is often used to describe any unknown thing, as in x-ray which were named this because the nature of the ray was initially unknown.

In statistics, letter such as; a,..x..,z, is a variable used to represent an unknown value.
The electrical symbol for a continuous or r.m.s. currentis an italic, upper-case, letter I. The symbol for an instantaneous value of current is an italic, lower-case, letter i.The symbol for its SI unit of measurement, the ampere, is an upright, upper-case, letter A.
Varible
A variable is any letter or other symbol that is used to represent an unknown number. "x" is the most commonly used variable, with y, z, n, a, and b also being prevalent. The objective of algebra is usually to find the value of a variable.
There are an infinite number of symbols that can represent value or value creation. You could use a bird as a symbol for example.
The term "What" is often used to represent the symbol or value that comes immediately before it in a mathematical formula or sequence. It is a placeholder that indicates a variable or unknown quantity in the context of the given formula.
Delta - Its the fourth letter of the Greek alphabet, and it is often used in mathematical expressions to represent the change (i.e. the delta) that occurs to a value.
