An expression.
A combination of numbers, a variable, and at least one operation can be represented mathematically as an expression. For example, in the expression ( 3x + 5 ), ( 3 ) and ( 5 ) are numbers, ( x ) is the variable, and the operation is addition. This expression illustrates how numbers and a variable can interact through mathematical operations.
