Part 1 of Evaluating Basic Algebraic Expressions; no negative numbers

  • How do you evaluate Algebraic expressions?
  • What does it mean to evaluate an expression?
  • How do you evaluate 4y^2 - xn if x = 2, n = 1, and y = 5?
  • How do you evaluate y/(x^2 + 1) if x=2 and y=5?
  • What does y/x - 2n equal if x = 2, n = 1, and y = 5?
  • How do you simplify and evaluate 3 + 2(n + y)^2 if n=1 and y=5?
  • How do you know what order to evaluate an expression?
  • How do you substitute numbers into variables to simplify expressions?
  • What does xy^2 - x^2 equal if x = 2 and y = 5?
  • How do you evaluate (n+y)/(n+x) if x = 2, n = 1, and y = 5?
This is a very basic math tutorial on how to evaluate basic Algebraic expressions given numerical values of variables. Variables are simply replaced by their values and the expressions are evaluated. Every step is shown in detail in each of six example problems.
