I love math and if someone asks me a question i know how to solve it in reasonable time. But when someone (like my younger sister who is in 10th grade homeschool math) asks me HOW to do it, i cant really explain. I only know how to do them. So i bought this to try and help her without giving her all the answers, apparently it worked. She went from a C in class to an A. Thanks! Now i can look forward to her having a better future, :) she wants to be a doctor someday.
