## Important Topics for Hall and Knight Higher Algebra Solutions Chapter 19: Inequalities

**Positive or Negative Quantities**

In the chapter, we shall suppose that the letters always denote real and positive quantities. For example, any quantity ‘a’ is said to be greater than another quantity ‘b’ when ‘a-b’ is positive.

Thus, any positive number is greater than -1. Also, -5 is less than -2 because -5-(-2) is -3, that is negative. Based on this definition, n we can say that zero is greater than any negative quantity.

**Inequalities and Linear Equations **

The chapter inequalities concentrate on solving equations. This concept is all about solving inequalities by studying the basics of the concept.

We know that a<b which to an extension can also be written as a ≥ b. This term demonstrates that either a is greater than b or equal to the value of b.

Now you will study how to deal with the two inequalities that are >(greater than) or ≤ (less than or equal to).

You might also get to solve double inequalities so while solving them ensure to focus on the inequalities that are in the original problem. Here is an example of these types of questions from the chapter: If -1<x<4, then determine a and b in a<2x+3<b.
