    • 2.1: The Multiplication Table
    • 2.2: Absolute Value
      Every real number can be represented by a point on the real number line. The distance from a number (point) on the real line to the origin (zero) is what we called the magnitude (weight) of that number in Chapter 1. Mathematically, this is called the absolute value of the number.
    • 2.3: Formulas from Geometry
      We review some well-known formulas from planar geometry.
    • 2.4: The Pythagorean Theorem
      The Pythagorean Theorem relates the lengths of the legs of a right triangle and the hypotenuse.
