## What are inequalities in math?

This chapter is about inequalities — statements that show the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. These are similar in form to the equations learned in chapter one, with one key difference: here, we are dealing with un equal quantities instead of equal quantities.

### Why is it important to understand inequalities in science?

Inequalities appear in a variety fields — math, physics, chemistry, biology, economics, business — as well as in everyday tasks like cooking, spending money, and driving, for instance. Thus, it is useful to understand them and to know how to work with them.

#### What is the inequality 34-12 > 5 + 2?

An inequality is a statement that shows the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. Like an equation, an inequality can be true or false. 34 – 12 > 5 + 2 is a true statement.

How do you know if an inequality is true or false?

Like an equation, an inequality can be true or false. 34 – 12 > 5 + 2 is a true statement. 1 + 3 < 6 – 2 is a false statement. 1 + 3≤6 – 2 is a true statement. 1 + 3≠6 – 2 is a false statement.

inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

## What are the 5 inequalities?

The 5 inequality symbols are less than (<), greater than (>), less than or equal (≤), greater than or equal (≥), and the not equal symbol (≠).

### What are inequality used for?

In mathematics, inequalities are used to compare the relative size of values. They can be used to compare integers, variables, and various other algebraic expressions.

#### How to plot an inequality on a number line?

To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle.

What is the difference between an equation and an inequality?

It’s like and equation, but with the inequality symbols, which are < and >. An equation uses an = (equal sign). 3x + 8 = 2x – 4 is an equation. 3x + 8 > 2x – 4 and 3x + 8 < 2x – 4 are inequalities.

How do you swap an inequality with a negative number?

But remember, when you multiply or divide both sides of an inequality by a negative number, you swap the inequality. So if we divide both sides of this by negative 3, we have to swap this inequality.
