Study Notes
Order of Operations
- A set of rules defining the sequence for solving mathematical expressions.
- Crucial for ensuring consistent and correct results in calculations.
Steps in Order of Operations
- Four main steps to follow:
- Parenthesis first: Solve expressions within parentheses.
- Exponents: Calculate powers or square roots.
- Multiplication and Division: Perform these from left to right.
- Addition and Subtraction: Complete these last, also from left to right.
Variables
- Symbols used in mathematics to represent changing quantities.
- Common examples include letters such as a, b, and x.
Constants
- Fixed numerical values that do not vary during a mathematical operation.
- Illustrative examples include numbers like 1, 3, and 10.
Algebraic Expression Simplification
- The statement "3x + 7 + 10x" is not considered simplified.
- Requires combining like terms to achieve a more concise expression.
