One reason to use a single letter to stand for a number is if the number is an unknown. Like if you say "In 2*n is 14, what is n?" It is just more convenient to have a short way to write the number. Another reason to use a single letter to stand for a number is if you are giving a formula for somehing that's true about every number. This is using n as a variable. Here is an example. "If the edges of a square are each n inches long, then the area of the square is n*n square inches." You might see this as an equation: A = n*n I hope this makes more sense to you now. - Doctor Mike, The Math Forum http://mathforum.org/dr.math/
