When an algebraic expression is composed of parts connected by + or - signs, these parts, along with their signs, are called the terms of the expression. This is because when x = -2, the denominator of the expression is 0, which would make the expression undefined. An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc. Note: dividing by a fraction is the same as multiplying by the reciprocal of the fraction.

If you feel difficulty in solving some tough algebraic expression, this page will help you to solve the equation in a second. This concept can also be used to simplify variable expressions. 1 . The same argument applies to other real numbers. If the denominator is zero, the rational expression is undefined. The structure of defining math expression advances in different grades. Rather than computing each exponential term and multiplying or dividing manually, simply add exponents when multiplying and subtract when dividing to save time. Solving for x gives us x = 7.
