First, lol I am female. And the reason we cannot explain how to solve the problem is we really do not understand how we get the answers. The answer we get is 100% correct every time but it is not by any taught formulas. When both of us were in school math was boring. When worksheets were handed out we had them completed before the teacher finished handing them out to the class. That is because we knew this stuff at least 2 or 3 years before. My son was in a private school and they allowed him to work at his own pace one year. He did 3 math classes in 9 months.
