Wow for your thinking and educating your daughter! My suggestion is whatever she like, if she like abacus then go ahead, if she like Vadic then go ahead for it too! But I prefer following should be included while teaching: #1. Knowledge of 0 to 9 and how 0 to 9 pattern repetition make infinite number (Just show her magic of number in easy and interesting way) #2. Simple basic calculation of Addition, Subtraction and just a base of Multiplication and Division (Just base because I found Mul, Div is difficult to understand and explain as far as i know) with finger or with out use of any tool just mentally. Like 5 + 2, then she can able to reply with 7 without using of pencil and paper every time. #3. How to read number like - 345 Should be read as three hundred forty five (If she know Hindi then also teach in Hindi like teen sau paitalis) etc. #4. What place should call in digit such as 3 should be considered as hundred, 4 should considered as tenth and so on. #5. Also give basic of Roman number so she can able to write number in three way - Hindi, English and Roman.

Spyware is one type of software used for spying purpose. For example, Keylogger software also consider as spyware. What it will do is, one it installed on your computer it will record/save all the things that you will type on keyboard and once you connect to internet all the typed thing will send it to me(if i installed spyware on your computer) including all password that you type at google, Facebook and banking.

Basically you can go with Java, But if you are coming from web development background then you can develop app with HTML, CSS and JS with PhoneGap framework. Or if you are coming from Microsoft technology then you can go with - C# and XAMRIAN Or if you are coming from System programming then you can go with - C and C++ with NDK (Native Development Kit) I am not sure with Dart Programming Language but google also thinking this language for apps development as they are facing issue with Oracle, Inc. for Java license issues in court.
