Smart Guide to High School Math is a book designed to cut to the chase and enable all levels of students to get what they need - and only what they need - out of high school math. Some students will only need enough algebra to get past an exit exam, but some students will want to prepare for careers in which math plays an important part.Some students have a natural talent for doing mathematics, but to many students math courses seem to be a bewildering array of unrelated formulas and techniques that have to be memorized - and are often forgotten during an exam, just when they are most needed. Smart Guide to High School Math shows you the organizing principles and key ideas that simplify algebra, geometry, and trigonometry, enabling you to get much more out of your math class - including higher grades - with less work.The dirty little secret that all math teachers know is that math is easy when you understand it - and very difficult if you don't. Countries such as Japan, Singapore, and Hong Kong traditionally score well on international math comparison studies.. These countries teach students the basic principles and how to use these principles. They teach math in depth rather than teaching a huge amount of material. In math, the most important thing is to know a few ideas really well. Smart Guide to High School Math tells you exactly what these ideas are. You still have to work - but you won't have to work as hard and you'll get a lot more out of your courses.
