Lesson Summary:

In this lesson on elementary algebra, we learn how to simplify polynomials by combining like terms. By adding coefficients of the same variables, we can simplify and write the expression in a simpler form. Examples range from simple expressions, like 4x + 10x - 2x, to more complex ones involving decimals and multiple variables. Remembering to line up decimals and dealing with positive and negative numbers are also emphasized in this lesson.
