    • 3.1: Decimal Notation and Place Value
      Recall that whole numbers are constructed by using digits.
    • 3.2: Adding and Subtracting Decimals
      Addition of decimal numbers is quite similar to addition of whole numbers. For example, suppose that we are asked to add 2.34 and 5.25. We could change these decimal numbers to mixed fractions and add.
    • 3.3: Multiplying Decimals
      Multiplying decimal numbers involves two steps: (1) multiplying the numbers as whole numbers, ignoring the decimal point, and (2) placing the decimal point in the correct position in the product or answer.
    • 3.4: Dividing Decimals
      In this and following sections we make use of the terms divisor, dividend, quotient, and remainder.
    • 3.5: Fractions and Decimals
      Recall that whole numbers are constructed by using digits.
