I will guide you in answering all the questions above and more in these lessons. The idea of Build Your Own Math is for you to find solutions by discussion and trial and error. I am there to present the problem and help you when you need it. And most importantly, ask the question: Why? Whether you get the answer right or wrong, you must explain how you got there. Then we need to determine if the solution was correct through discussion. Remember, there can always be more than one way to solve things!
