The goal of studying geometry, algebra and trigonometry

Goal of this math website: This math website is designed to help all middle and high school students to better understand algebra, geometry and trigonometry. There are multiple examples designed for students to practice how to analyze math problems and solve them. Help students build a very solid background for college study and improve students testing scores in the standard test.

Most importantly, mathematics can train our brain. By learning mathematics, we can obtain the logical thinking skills which can be apply to our life. For example to make a physical product, we need at least to know its principles of mathematics. Learning mathematics will help students have more options for their career and help them build self-confidence.
