printing Calculator

Cannot multiply using keyboard. App should be removed from site. Do not buy!

I was expecting a substitute for an adding machine sitting on my desk. No setting to Add 2 for decimal point. The app won't recognize the asterisk for multiplication. Absolute waste of money.

It's a good calculator, I like the printing function. The only thing that, I can't type in my own decimals. Example: I can't type if I'm adding like dollar amounts, I cant do 150.35.

I need a guide to the keys
