Digital Portfolio: Pre-AlgebraThis is where I will place all of my produced digital content for my Pre-Algebra class. I have Pre-Algebra 4th Period.
Right now we are learning about inequalities, how to solve them, and how to graph them. Soon we will start a new chapter in our Math book. |

Inequalities

In Math we are currently studying inequalities and equations with rational numbers. Most recently we've learned what inequalities are.
In short, an inequality is like an equation but without an equals sign. Inequalities show numbers that are inequal, hence the name. We've also learned to graph them, as shown in the picture to the left. Graphing inequalities is easy once you've got the method down. To graph an inequality, look at the inequality itself. If the variable is on the left-hand side, then write the constant (or real number) down on your graph and make an arrow in the direction of the "greater than" or "less than" sign. Make a circle on your constant's graph point. If the inequality includes "or equal to" then fill in the circle.
This skill seems pretty useless from afar, but it can be applied to many real-life situations, too. For example, if there are at most 35 people allowed on a roller coaster train at the same time, this is an inequality. It is written as "x is less than or equal to 35".
This skill has also helped us with graphing. Using a graph is a lot easier once you have experience with it using skills you've already learned. The little lines on our graph composition books are much more convenient and useful using this. I hope I'm able to put my experiences with inequalities into use sometime in the future!
