Background Tutorials

Apply the properties of operations to generate equivalent expressions.
- How Do You Use the Distributive Property to Simplify an Expression?
  
  In this tutorial you'll see how to apply the distributive property. Remember that this is important when you are trying to simplify an expression and get rid of parentheses!
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
- What are Like Terms?
  
  Combining like terms together is a key part of simplifying mathematical expressions, so check out this tutorial to see how you can easily pick out like terms from an expression
Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
- How Do You Subtract Two Rational Expressions with Different Denominators?
  
  Subtracting rational expressions? Don't have common denominators? No problem! Find the least common denominator (LCD) and change each rational expression into an equivalent expression with that LCD. Once you have common denominators, you're ready to subtract and simplify! Watch it all in this tutorial!
- What's a Rational Expression?
  
  Got a fraction with a polynomial in the numerator and denominator? You have a rational expression! Learn about rational expressions in this tutorial.
