# Pre-Calculus

## By phoneflips

#### Description

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.

##### Amazing

This thing breaks it down to where an idiot could understand pre-calc. I misses a lot of my pre-calc class this semester if I had had this thing sooner I'm positive I would have done way better than I did on my final. Things I didn't understand before now seem so simple to grasp, definitely worth the price!!

##### Helped with my exams

This puts everything out in an easy to read format with the formulas. Instead of going through 100's of pages to make my cheat sheet for my finals and it was all readly available in moments

##### This is comprehensive

This is everything you need in a short easy to sort list. I took pre cal already (I'm on my second time around) and this is easier than any text book that I paid over 100 for. Now I need my physics app lol
