About This Site
This site is about my Math Apps for iPhone. It all started when I was looking for a Column Addition app for my daughter. I was surprised to find out that there were no apps that teach the basics like column addition, column subtraction, long division and long multiplication. I had experience about designing visualizing algorithms for computer science students. I decided to use that knowledge to make great teaching and learning apps for children and everybody who wants to study math. You wil find my apps by choosing the my apps -link.
