The calculator app allows you to enter numbers from the keyboard, but doesn't allow you to use the equal sign from the keyboard. You have to click the = in the screen image. This is very cumbersome. Also, there is no way to clear the material to be printed, other than to quit the application and start again. This app is disappointing.

This version works with a Mac extended keyboard! Yes! Nice calc.

I have an apple USB keyboard with 10 key and half the buttons dont work with this app. The plus key, multiply key, and clear key doesn't work. plus the button placement of the app does not correspond with the placement of the keyboard. (multiply, divide, add, period, equal, and subtract are all in the wrong places)the only cool feature is that you can print the calculations, but with the limitations it won't be useful. Also, it should have the auto decimal feature to be a real emulation of a printing calculator (that will automatically insert the decimal two digits from the right if you don't hit the decimal key).

Such a simple app, yet it doesn't work well at all. You cannot resize the print area to see more than a few lines. Once you press the = or ENTER keys, you will get an answer, but it will not carry forward into the next calculation (you have to enter the starting number all over)…not very practical for use. Save your money until they fix this one….
