Question

Is it necessary for an algebraic expression to contain any mathematical operator?

• A. yes
• B. no
• C. depends
• D. can"t say

Answer 1

The correct option is B no

An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). Thus it is not necessary for an algebraic expression to contain a mathematical operation.

E.g. $x$ is an algebraic expression not containing any mathematical operators.
