READ THIS FIRST This is a special type of calculator invented by a polish mathematician in 1920. It can be extremely useful at times, and once you get the hang of it, it can prove far more useful than a regular calculator. One major benefit is that you don't need to use parentheses. Here is how to use it: The value at the top of the calculator is the number you are typing in. Once you have typed in the number you want click the enter button. Then the number you just inputted will appear just below that. You can enter as many numbers as you want. Then when it comes time to use the desired operation click the button. This will do the operation you just clicked to the last two numbers you put in. For example: If I did 3 enter; 4 enter; 5 enter; then clicked * (multiplication), I would get 20 as my answer because it just multiplied the last two numbers I put in (4 and 5). However if I did 4 enter; 5 enter; 6 enter; then clicked * twice I would get 120 because 5*6 = 30 and 30*4 = 120
Thanks to my dad for introducing me to the reverse polish calculator Feel free to use for homework :D
