MyScript Calculator is another great maths based app. Do you rememebr when you got told that you may not always have a calculator and had to understand how to calculate? or even that you needed to know a reasonable amount of syntax for a calculator to use it? well this app may be a game changer for some, a handwritten based calculator – put in your question and see your handwriting interpreted and a result given.
Available for both iOS and Android this app is quick to use and easy to make adjustments by just scribbling out a number and overwriting, for more info see here – http://www.myscript.com/calculator/
