Calculator+ HD

This calculator meets my needs. It is not only a basic calculator but, has different modes that come in handy doing school work.

It can't handle numbers as small as 10^-20 (gives error) even though can handle large numbers like 10^27. Strange and confusing arrangement of function keys: for example, trig functions sin, cos and tan are scattered all over the keypad. No reciprocal key (1/x). Looks like another scientific calculator designed by tech nerds who are good at programming, but aren't very familiar with scientific/engineering calculations.

It's an excellent calculator, but it could use better graphing capability

this helps a lot in my homework :D

No ability to copy or paste from the desktop. No ability to +M only one C (clear) key with simple clears off the formula. No ability to past results into Excel or other desktop apps. This may have been a learning app for a programmer but stick with the old calculator if you work from the desktop in Windows 8.1

Doesn't explain how to use it very well. On the top of the calculation box is the buttons to change from standard to scientific. I still can not find where it will change into a Graph for me. And when you go to the website for help it takes you to this weird blog.
