Qama Tried the actual calculator about 2 years ago. A great concept and brilliant to have it as an app. I will advertise this to all my classes.
Great calculator, i will use to exercise my brain :). Regards from Mexico City.
Wow! finally a calculator that helps you think before you just mindlessly tap in a calculation. And I've never played with a calculator on the train before, just for fun! Love how tapping in 5 x 6 for example, needs you to tap in the exact answer. Really helps younger ones remember their tables in a quiet way. This should be in EVERY school.
