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.
