Main Concepts and Results
Algebraic expression is formed from variables and constants using different operations.
Expressions are made up of terms.
A term is the product of factors. Factors may be numerical as well as algebraic (literal).
Coefficient is the numerical factor in a term. Sometimes, any factor in a term is called the coefficient of the remaining part of the term.
The terms having the same algebraic factors are called like terms.
The terms having different algebraic factors are called unlike terms.
Expression with one term is called a ‘Monomial’.
Expression with two unlike terms is called a ‘Binomial’.
Expression with three unlike terms is called a ‘Trinomial’.
In general, an expression with one or more than one term (with non- negative integral exponents of the variables) is called a ‘Polynomial’.
The sum (or difference) of two like terms is a like term with coefficient equal to the sum (or difference) of coefficients of the two like terms.
When we add (or subtract) two algebraic expressions, the like terms are added (or subtracted) and the unlike terms are written as they are.
To find the value of an expression, we substitute the values of the variables in the expression and then simplify.
Rules and formulas in mathematics are written in a concise and general form using algebraic expressions.
