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.
In algebra, letters like a, b, x, y, all represent numbers. We use letters like this when we have an unknown number.
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.
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.
A letter used to represent a number is a variable of sometimes a constant.
The coefficient in algebra is the number before a letter with an exponent on it. The 3 is the coefficient in this example: 3x7
