An algebraic expression is a mathematical phrase that includes numbers, variables, and operation symbols.

A numeric expression is a mathematical phrase that includes only numbers and operation symbols, without any variables.

The term 'product' refers to the result of multiplying two or more numbers or expressions.

It is represented as n - 30, where n is the number.

An algebraic expression contains variables, while a numeric expression does not.

A variable is a symbol, often a letter, that represents an unknown value in an expression or equation.

Coefficients are the numerical factors that multiply the variables in an algebraic expression.

To simplify an algebraic expression means to combine like terms and reduce it to its simplest form.

A term is a single mathematical expression that can be a number, a variable, or a combination of both, separated by addition or subtraction.

To translate a verbal phrase into an algebraic expression, identify the operations and variables described in the phrase.
