With an adding machine, which is what this is, you enter the number followed by the + or -. If you wanted to add 10+20, you would enter 10 then + then 20 then +. This would show your answer. If you are using the printer and you wish to see the final answer on the paper, hit the * key and your answer will print.
If you are subtracting, let's say 100-40, you would enter 100 then + then 40 then - then *. Adding machines expect you to enter long strings of numbers to total. You may have both positive and negative numbers. So, you always enter the number first followed by either positive + or negative -.
You might have 100 + 25 - 37 - 1 + 50. For that enter:
100+25+37-1-50+ then *
Different than a calculator but the same for all "adding machines". This machine should really be called an adding machine since that is the kind of input it is looking for.
