It is now time to switch gears a little and start thinking about solving inequalities. Before we get into solving inequalities we should go over a couple of the basics first. It is also assumed that you know that. Likewise, it is assumed that you know how to deal with the remaining two inequalities. What we want to discuss is some notational issues and some subtleties that sometimes get students when they really start working with inequalities. Both of the following are true inequalities. The most common mistake is to decide that the first inequality is not a true inequality.
In algebra, letters are used to represent numbers. The letters used to represent these numbers are called variables Letters or symbols used in algebra to represent numbers. Combinations of variables and numbers along with mathematical operations form algebraic expressions Combinations of variables and numbers along with mathematical operations used to generalize specific arithmetic operations. The following are some examples of expressions with one variable, x :. Terms Components of an algebraic expression separated by addition operators. The numerical factor of a term is called the coefficient The numerical factor of a term.
