Study Notes
Algebraic Expressions
- Algebraic expressions are mathematical statements formed by applying operations (addition, subtraction, multiplication, division) to variables and constants.
- Example: If a pattern uses 4 matchsticks to represent 4, and 3 more matchsticks are added each time, the general expression for the number of matchsticks needed to represent n fours would be 4 + 3(n-1).
- An algebraic expression is also called a variable expression.
- It combines terms through different operations.
