Inaccurate!

Ignore the folks complaining about the number 2. If you can’t figure out how to enter a 2 without the actual 2 button, you need a tutor, not a calculator. No, the real complaint is that this application gets answers wrong. Lemme say it again, this calculator can’t do math. Probably because it doesn’t store large values properly, has no concept of scientific notation, and pollutes answers with machine error (look it up). What is 10 raised to the 25th power? According to this app, a bunch of 9’s, 4’s, 6, 7, and 5’s are needed in the answer. Seriously?? And if you evaluate a number that’s too large, it just returns “inf”. Infinity?? I don’t think so! Even if this wasn’t enough to chase you away, and it should be, it doesn’t have many built in functions other than trig, and those take up most of the keyboard. Switching between radians and degrees is also a hassle. But did I mention it gives wrong answers? Run away. P.s. (3-1=2) and (3333-1111=2222) now you don’t need the 2 key. But you do need a calculator that doesn’t give wrong answers.
Gotta pay to use the number 2??

This is a terrible way to implement “try before you buy”. Surely the developer could have come up with a better idea.
Great if you don't need the number 2

Hey guys, let's have all of the digits on the app, unless that is for the paid version only.
your worse then VALVe

At least valve knows 2 exists, but not 3. and you don't have to pay $3 to use #2
Get it together

If you even want this app to be successful or get decent ratings, I suggest you block something else besides the number 2. You set yourself up for failure as an app creator. People don't want to buy crap, so don't give them crap. The price is acceptable, just don't block the 2. I can't even purchase the upgrade anyways because this app is bad. Needs improvement
Rip off!! You have pay 2 dollars to unlock the 2 key!!

I download this app since we're doing exponential equation in school a need a high power calculator. I download in hurry while doing homework. I finally open up the app to do my homework later, when I had time, only to find that while had everything I need, THE NUMBER 2 KEY WAS MISSING!!! So, I clicked and it asked me to pay 2 dollars to unlock. This app is waste, unless you only need do equation that don't involve the number 2.
