What are Algebraic Expressions?
Algebraic expressions are mathematical phrases that can contain numbers, variables, and operation symbols. They are fundamental in algebra and are used to represent relationships between different quantities.
For example, in the expression 3x + 2, "3" and "2" are constants, "x" is a variable, and "+" is an operator.
Key Topics in Algebraic Expressions:
- Variables: Symbols, often letters, used to represent unknown values.
- Constants: Fixed numbers that do not change.
- Coefficients: Numbers that are multiplied by the variables.
- Operators: Symbols such as +, -, *, and / used to denote operations.
- Terms: Parts of an expression separated by + or - signs.
