    Introduction to Algebra

    • Constant : A symbol in algebra which had a fixed value.

    • Variable : A symbol which can be assigned different numerical values or whose values can vary is called a variable.

    • An algebraic expression is an expression composed of arithmetic numbers, letters , and sign of operation

    • A term is an arithmetic number,letter, group of letters, or group composed of an arithmetic number and letters which are joined by multiplication or division.

    • A monomial is algebraic expression of one term.

    • A binomial is an algebraic expression of two terms 

    • A trinomial is an algebraic expression of three terms. 

    • A compound expression or polynomial is an algebraic expression of two or more terms.

    • A factor is any one of two or more numbers that are multiplied together.

    • If two factors form a product, either factor is the coefficient of the other. Eg.in the product 9a, 9 is the coefficient of ‘a’, 9 is the coefficient of ‘a’ and a is the coefficient of 9

    • The number factor of ap product is the numerical coefficient of the remaining factors.

    • The letter factor or variable if a product is the literal coefficient.

    • Like terms or similar terms are terms which have the same literal factors.

    • Unlike terms are terms which have different literal factors.
