Calculus may not seem very important to you but the lessons and skills you learn will be with for your whole lifetime!

Calculus is the mathematical study of continuous change. It helps you practice and develop your logic/reasoning skills. It throws challenging problems your way which make you think. Although you may never use calculus ever again after school or college, you will definitely hold on to the lessons that calculus teaches you.

Things like time management, how to be organized, how to accomplish things on time, how to perform under pressure, how to be responsible are just some of the things Calculus helps you become proficient in. Traits that will help you succeed.

Calculus plays a big role in most universities today as students in the fields of economics, science, business, engineering, computer science, and so on are all required to take Calculus as prerequisites.

Our Pre-Calculus guide is a preliminary version of Calculus containing over 300 rules, definitions, and examples that provides you with a broad and general introduction of this subject. A valuable reference guide to have on your phone.

"After becoming familiar with the basics from other sources, one should check-out Pre-Calculus Guide to test definitions and conceptual understanding, just as you would refer to a text book. You will quickly be directed to the desired category, a series of well-documented procedures and examples that will assist the student navigate through these important topics." - www.appolearning.com
