- 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.
