[L.] The number prefixed to an algebraical symbol to show how many times the number denoted by that symbol is to be taken. Thus, if x denotes any number, known or unknown, 10x signifies a number that is ten times x, and 10 is said to be the coefficient of x in the expression 10x. A coefficient is not necessarily a whole number; it may be a fractional or incommensurable number, or even a number which is a combination of algebraical symbols, so that there are literal coefficients as well as numerical coefficients.
