My favorite calculator

I really like this calculator. It is easy to use and it keeps a tab so you can look to make sure that your numbers were entered correctly and delete the tab deleted when you are finished. I can also enter more digits than with the one I was given at work.

Best yet!

This is the best calculator app I’ve tried yet. I’ve tried others but this by far is the best. This may be a small thing, but I like how your subtractions are shown in red, and your additions are shown in black. This is very helpful when you have to look back at the tape.

I like it a lot

Very fast to initiate app. Large numbers, large buttons very easy to read. Very clean layout of keyboard.
The paper tape at the top is a God sent, you will never wonder if you have all the numbers entered just look on the tape. And best of all, NO adds like my last one had.
