This lesson teaches how to add and subtract algebraic fractions by finding the least common denominator. The instructor demonstrates a few examples and urges students to factor the denominator and then multiply both the numerator and denominator to get a common denominator. Then, each fraction can be put over the common denominator, and the numerators can be simplified by adding like terms. Finally, the instructor encourages students to factor the numerator to check if anything cancels out.
