    • 4.1: Volume
    • 4.2: The Pythagorean Theorem (optional)
    • 4.3: Evaluating Algebraic Expressions
      In this section we will evaluate algebraic expressions for given values of the variables contained in the expressions.
    • 4.4: Combining Like Terms
      A term is a single number or variable, or it can be the product of a number (called its coefficient) and one or more variables (called its variable part). The terms in an algebraic expression are separated by addition symbols.
    • 4.5: Adding and Subtracting Polynomials
      Recall that we combine like terms, or terms with the same variable part, as a means to simplify expressions. To do this, add the coefficients of the terms to obtain a single term with the same variable part, but the variable part does not change. This, in addition to the commutative and associative properties of addition, allows us to add polynomials.
    • 4.6: Multiplying Polynomials (optional)
    • 4.7: Dividing Polynomials
    • 4.8: Prelude to Solving Linear Equations
      Law enforcement and the military are using drones rather than send personnel into dangerous situations. Building and piloting a drone requires the ability to program a set of actions, including taking off, turning, and landing. This, in turn, requires the use of linear equations.
    • 4.9: Strategies for Solving Applications and Equations
      Now that we can solve equations, we are ready to apply our new skills to word problems. We will develop a strategy we can use to solve any word problem successfully. At the end of this section is a huge list of practice situations to test your problem solving process. Keep practicing! Don't give up if you get a few wrong.
