In an expression where numbers and variables are being multiplied, each of the values being multiplied is called a factor. A multiplicative expression has anywhere between 2 and infinitely many factors; the result of multiplication is called a product. Factor2××Factor3××Factor4==Product24 Each part of a multiplicative expression that includes variables is also called a factor. Factor2⋅⋅Factorx⋅⋅Factor4==Product8x When multiplying algebraic expressions, each expression is also called a factor. (x+2)Factor(x+1)Factor=x2+3x+2Product
