Really cool and promising idea

It reminds me of school and doing calculations on paper at home. Really cool and much better than those old one-line calculators. So, consider a full keyboard support and a more powerful calculation engine. And keep implementing such promising stuff.

Pretty awesome

This app kicks the butt of most calculator apps and most graph paper apps - but with some minor issues. It does not perform square root calculations, like the photo suggested. It can't do exponents. It's mostly for quite basic calculations - but still, it is good enough to merit three stars - four, if you're feeling generous, like I am.

Better than any calculator App

Beats most calculator apps because it's basically like a blackboard that answers back.
