Advent Wreath Candles. Set on the branches of the wreath are four candles: three purple candles and one pink candle. In the center of the wreath sits a white candle. As a whole, these candles represent the coming of the light of Christ into the world. On the first Sunday of Advent, the first purple candle is lit.
In mathematics,  a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.
A term can be a signednumber, a variable, or a constant multiplied by a variable orvariables. Each term in an algebraic expression is separated bya 1 sign or 2 sign. In, the terms are: 5 x, 3 y, and 8.When a term is made up of a constant multiplied by a variableor variables, that constant is called a coefficient. In the term5 x, the coefficient is 5.In some terms, the variables will have exponents, such as .This exponent determines the degree of that term. â¢ The degree of is 2.
