Study Notes
Whole Numbers
Definition
- A whole number is a positive integer, including 0, without fractions or decimals.
Properties
- Closure: The result of adding or multiplying two whole numbers is always a whole number.
- Commutative Property: The order of whole numbers being added or multiplied does not change the result.
- Associative Property: The order in which whole numbers are added or multiplied does not change the result.
- Distributive Property: The multiplication of a whole number over the addition of two whole numbers is equal to the sum of the multiplications.
Operations
- Addition: The result of combining two or more whole numbers.
- Subtraction: Finding the difference between two whole numbers.
- Multiplication: Repeated addition of a whole number.
- Division: Repeated subtraction of a whole number.
Exponents
Definition
- An exponent is a small number that indicates the power to which a base number should be raised.
Rules of Exponents
- Product of Powers: a^m × a^n = a^(m+n)
- Power of a Product: (ab)^m = a^m × b^m
- Power of a Power: (a^m)^n = a^(mn)
- Zero Exponent: a^0 = 1 (except for 0^0, which is undefined)
- Negative Exponent: a^(-m) = 1/a^m
Applications
- Simplifying Expressions: Using the rules of exponents to simplify expressions with exponents.
- Solving Equations: Using exponents to solve equations involving exponential functions.
Note: These notes provide a concise overview of whole numbers and exponents. For a more comprehensive understanding, it is recommended to practice problems and explore additional resources.
