Study Notes
Algebraic Expressions
- An algebraic expression is an expression that includes variables, constants, and mathematical operations.
Identifying Variables and Constants
- In the expression $x + 5$, $x$ is the variable, which is a symbol that represents a value that can change.
- In the expression $x + 5$, $5$ is the constant, which is a value that does not change.
Exponential Notation
- Exponential notation is a shorthand way of writing repeated multiplication of a number by itself, for example, $2^3$ means $2 \cdot 2 \cdot 2$.
Treating Constants and Variables in Algebraic Expressions
- In algebraic expressions, constants and variables are treated differently: constants have fixed values, while variables can take on different values.
