I have a New Sharp Adding Machine. I thought it would replace my calculator and make balancing my accounts faster and easier. Boy, was I wrong!
I cannot get it to start from a number and begin to subtract. It will take off the whole amount and want to add. Adding works. But the Subtracting does not do the reverse. I think I may have to send it back. Does anyone here have one and use one?

Adding machines use different logic for how you input calculations.
To subtract 10 from 23 on a regular calculator you'd input: "23 minus 10 equals" and get your result.
The same calculation on an adding machine would be:
"23 plus 10 minus" which basically states you're adding positive number 23 from zero and then adding a negative number 10. It seems a bit awkward at first, but once you get the hang of things, you can do calculations on an adding machine much faster.
Good luck.
Looking for a manual for the above adding machine. Directions liost and cannot feed paper
