I am looking for a calculator which can do calculations in the terminal itself, without any other extra prefixes and suffixes.
For example: If I typed something like 10000-9000 in the terminal, the answer should come out as 1000.
Once again I am saying, I just need a quick calculator in the terminal, without any characters added. I know if I switch to Python, it can do that, but I don't want it in such a way.
