What is a variable expression in algebra. A term is a single number variable or a number and a variable multiplied together. What is an algebraic expression. Variable expressions are expressions that involve variables which are symbols that represent changing quantities.
The letter o is usually not used because it can be mistaken for 0 zero. Examples of variable expression. The basic building blocks of an algebraic expression are variables and constants and operating symbols such as plus minus signs.
A variable expression is a combination of numbers or constants operations and variables. For example let s say with have the equation x 5. 4 cdot x 3 a variable as we learned in pre algebra is a letter that represents unspecified numbers.
Example of a variable expression. An algebraic expression comprises both numbers and variables together with at least one arithmetic operation. Variables are important to know for higher levels of math and are even used similarly in other subjects like computer science.
