        Algebraic expressions

                   So what do letters in algebra mean? Until now- in basic arithmetic -you work with numbers , each number having a specific value or meaning.A  "2"  is 2 , for example .A is "2" is always a2-it is never 6and it  is never 10.It's like that for all numbers. We still use regular arithmetic numbers in Algebra.


A polynomial is an expression that is constructed from one or more variables and constants, using only the operations of addition, subtraction, and multiplication (where repeated multiplication of the same variable is standardly denoted as exponentiation with a constant non negative integer exponent). For example, x^ + 2x − 3 is a polynomial in the single variable x.
