Oh, dude, in math, a symbol that represents a quantity is called a variable. It's like a mysterious letter that stands in for a number, kinda like a math magician pulling numbers out of a hat. So, next time you see a letter in a math problem, just remember it's not trying to confuse you, it's just playing the math game.
A math expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities.
In math a letter is a variable and it can be any number.
If you mean the symbol of a triangle, in math and science a triangle stands for change in
You add and then solve the math
Nobody 'invented' it... letters are often used in maths to signify an unknown quantity.
In mathematics, a variable is a symbol that represents a quantity that can change or vary in a given problem or equation. Variables can be used to denote unknown values or to represent values that depend on other factors. They are commonly denoted by letters such as x, y, or z.

If you mean a variable then it is an unknown quantity that can represent many values until its specific value is determined usually by solving an equation.

It is (or they are) unknown!
The symbol that you describe seems to be the greek letter Phi. It is normally used to indicate a variable that is an angle, just as x is used to indicate a variable that is a numeric quantity.
If you are talking about math then its usually " x " but if that is already use in the expression and you want to use another symbol to represent a DIFFERENT number then you can use y or a or so on.
