Algebraic expression
An algebraic expression is a mathematical phrase that contains variables, numbers, and operations
An algebraic expression is a mathematical phrase that contains variables, numbers, and operations. It is different from an equation as it does not have an equal sign (=) and is not solved.
Algebraic expressions can be as simple as a single term or can have multiple terms connected by mathematical operations such as addition (+), subtraction (-), multiplication (×), and division (÷). Variables, usually represented by letters like x, y, or z, are used to represent unknown quantities.
For example, the expression 3x + 5 is an algebraic expression where 3 and 5 are constants and x is the variable. The expression 2x² – 3y + 7 is another example with multiple terms and variables.
Algebraic expressions are used to represent relationships, formulas, and general mathematical situations in a concise way. They can be evaluated, simplified, and manipulated using algebraic rules and properties.
