A letter that is used in place of a numeral is generally called a variable. You can use any letter to represent a numeral, but the most commonly used letters are a, b, c, n, x, y, and z. If the two inuend and subtrahend, addends, factors, or divisor or dividend are both represented by a variable, then it is impossible to tell what the variables stand for. For example, there is no way to tell what a and n stand for in a-n=0. A and n can stand for 5 and 5, or 9 and 9, or anything! Since the difference is 0, then if n=a, the equation would be true!
