a variable
Variable: A letter or symbol used to represent a number or quantities that vary
variable
The letter that represent the composite number is letter C.
The point of using letters in algebra is that they can stand for any number (or a range of numbers that are, as yet, unspecified). There is no specific letter allocated to a number.
An unknown number
It is called a variable.

I'm not sure if there is a number but the algebra is just a simple "N" for "number"
An unknown number
Yes, if you know the number and the letter's number, then you multiply them together.
The coefficient in algebra is the number before a letter with an exponent on it. The 3 is the coefficient in this example: 3x7
A letter used to represent a number is a variable of sometimes a constant.
A letter used to represent an unknown number is called a "variable." In mathematics, variables are often denoted by letters such as x, y, or z. They are used in equations and expressions to stand in for values that can change or are not yet known. Variables play a crucial role in algebra and various branches of mathematics.
