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
