Question

An algebraic expression consists of

• A. Constants
• B. Arithmetic operators
• C. Variables
• D. All of these

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Constants

B

Arithmetic operators

C

Variables

An algebraic expression is a mathematical phrase consisting of constants, variables and algebraic operators(eg. ${}^{\prime }{+}^{\prime }$ and ${}^{\prime }{-}^{\prime }$).

They do not have an equality sign $(=)$, which makes them different from algebraic equations.

In the expression 4x+7, 'x' is the only variable, ${}^{\prime }{+}^{\prime }$ is the operator, $7$ is a constant and $4$ is the coefficient of the variable ${}^{\prime }{x}^{\prime }$.
