Basic Maths – Exponents And Order Of Operations DVD –  

Exponents & The Order Of Operations: This lesson introduces two important pre-algebra topics. The first exponents or powers are used to simplify repeated multiplication. The vocabulary of exponents is discussed. Patterns in powers of various numbers are discovered. The various properties of exponents are studied. This study is not based on memorization. Instead a logical approach is used for working with exponential numbers. The second topic is the order of operations. The rationale for the PEMDAS (parentheses exponentiation multiply/divide add/subtract) rule is discussed and problems are used to reinforce the process. You Will Learn: 1. To explain the meaning of the word exponent. 2. To multiply numbers given in exponential form with the same base. 3. To divide numbers given in exponential form with the same base. 4. To simplify an expression that has a base raised to a power raised to a power. 5. To simplify an expression using the proper order of operations.
