An expression is made up of numbers and variables joined by mathematical operations.
An algebraic expression is a mathematical phrase that includes numbers, variables, and operational symbols.
A mathematical phrase that includes operations, numbers, and/or variables is called an "algebraic expression." For example, the expression (3x + 5 - 2y) consists of numbers (3, 5, -2), variables (x, y), and operations (addition, subtraction). Algebraic expressions can represent a variety of mathematical relationships and can be simplified or evaluated for specific values of the variables.
variable expression(;
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2
