About Touch Abacus APK
Table Of Contents
Description
A simple Touch Abacus aimed for the development of number sense in early math learning. The abacus has a long history in various cultures and is both concrete and abstract in some sense. This app provides the Chinese and Japanese versions. The Chinese abacus has seven beads on a vertical bar, while the Japanese version has five beads on a vertical bar. As a general rule, each bead in the lower deck represents one when moved toward to center beam. Each bead in the upper deck represents five when moved to the center beam. On the Japanese abacus, each bar could represent zero to nine units. By contrast, the Chinese abacus allows the representation of zero through 15 units on each bar, thus supporting calculation using the base-16 system. For the base-10 system, the two beads at the very top and bottom are not used. About the decimal point, users could, in fact, choose their own place, depending on their specific needs. This abacus app is developed by Dr. Lingguo Bu (lgbu@siu.edu) using MIT AI 2, free for educators. Have fun playing with math.Latest updates

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
