While many English teachers might consider Spark Notes a distraction and a bane, it turns out that the Math section of this well-known tool's website offers some excellent resources for everything from pre-algebra to relatively advanced calculus. Students who are in need of some easy to follow math tutoring may find the site especially helpful. Selecting any of the several dozen sections on the main page navigates to an in-depth treatment of that topic. For instance, the Operations area under Pre-Algebra opens to a General Info Section and then eight different topics (Order of Operations, Problems, Properties of Addition, Problems, etc.), each featuring step-by-step explanations. While the math presented here is clearly best learned with a good teacher and a great textbook, the SparkNotes site proves surprisingly helpful as a supplement.
