I don't like doing math. Instead, I give all of my logic to the machine computer and save none of it for myself. I also don't like having to leave the terminal, so if I could do my math there too, that'd be ideal.
It'd be neat if, given a string of math, we could also be given the output. So, given the string 1+1 you should be able to print out 2.
$ ./program 1+1
2 Next, consider multiplication and division. From elementary math, you should remember that multiplication and division come before addition and subtraction. So 1+1*2 would return 3.
$ ./program 1+1*2
3 Suppose we wanted to do the 1+1 first. We could surround 1+1 with parentheses.
$ ./program (1+1)*2
4 These are simple examples, but something like 2*8-12/(2+4) would return 14.
The requirements for this challenge are as follows:
As someone that can't do quick maths,
I would like to be able to put my equation into a program that does the maths quick
so that I don't have to do the maths
- You don't have to worry about spaces. For example, always expect
1+1instead of1 + 1. - Your program will be a command line application. However that manifests is up to you, but it should be runnable from the terminal.
- You can expect simple addition, subtraction, multiplication, and division.
- It is possible for parentheses to be nested like this:
1+(3*(1+2))-8.
Deploy your application for other people to use.
