Wow really awesome place value adding. I have a question for you. Have you ever thought about why it is important to use place value? Why do you think it's important that we keep numbers in their right spot? -Mrs. Maley

Thank you!! No, I actually have never thought of that. I think it is important because if you don't you could be mixing up the number or adding, subtracting etc. it wrong. Also you might really need to know the answer. -Adriana
