This lesson introduces the terms
constant, variables, and algebraic expressions.
To better understand the lesson, let us describe the terms related to Algebra.
associated with algebra such
as
one or more than one value. These
Variables - are symbols or letters that may
variables may represent elements of the set of real numbers.
Constant- numbers or symbol which has a fixed numerical value.
For example: 2, 5, 0, -3, -7, etc. are constants.
In 2a, 2 is a constant and a is a variable.
In -7mn, -7 is a constant and m & n are variables.
Term - is a constant, a variable, or a product or a quotient of constants and
variables. Terms are separated by the symbols plus or minus sign.
