Show that if a 1, a 2…. an are n distinct real numbers, exactly n ? l multiplications are used to compute the product of these n numbers no matter how parentheses are inserted into their product. [Hint: Use strong induction and consider the last multiplication.]

Introduction to Chapter 1: Difference of Squares: a -b =(a-b)(a+b) Zero Product Property: ab=0; a, b=0 1.1 Linear Equations are first-degree equations in one variable that contain the equality symbol, “=”. Linear equation in the variable x can be expresses in the standard form, ax+b=c, where a ≠, b ∊ ℝ The domain is...
