Mathematic Problem Solving (Just for Indonesian)

OK, here is a new post. According to my survey, I found that so many people get problem in mathematic. It really makes me shocked. As a solver, I thought the way to help them. Finally, I found the way.

The way is by making a mathematic program for them so they can do their task easily and efficiently. For that, I made the program for 5 days. Actually it was easy, but it really need to think. 

If you are interested, just click here to get the program. It is just a small file. I made it with VisualBasic 5.0. Oh, there's important one. It is in Bahasa Indonesia (Indonesian Language), so sorry for those foreign countries. Thank you.
