Algebra is a key Math skill that is used in all Math courses and many other disciplines. Algebra is like grammar, punctuation and spelling in English - key skills without which you wouldn't be able to write a great essay. The trick with learning algebra is to start small and build your skills slowly. In this course we begin with some basic algebra moves like simplifying algebraic expressions and grow skills one at a time. Before long you'll be solving equations, creating graphs and working with Mathematical functions.

What You'll Take Away From This Course
Precalculus is a challenging but rewarding course with a lot of content. By mastering some core techniques you'll be able to answer a wide variety of questions both in class and in the real-world. Each instructional video teaches one primary skill and mixes a small amount of theory with example problems. You will then practice what you've learnt in the end of section review exercise. I've also included step-by-step solutions so you can check your work as you go. Take this course and you will learn:
The foundations of Mathematical functions
Core function techniques such as composite / inverse functions, function graphs, and domain / range
Equation solving skills - a fundamental Math skill at all levels
Polynomials - one of the most common types of function
Specific functions such as exponentials / logarithms / trigonometric
Mathematical series - a key concept / techniques for more advanced Math courses
