So what is stopping you? Snark aside, this can get really complicated unless you make some well defined rules. This becomes difficult especially when you think about whether you want to support order of operations. Should “1+3*2” generate “7” or “8”? Do you want to support longer expressions or just 2 operations? Personally, if I were learning the language I would make it do 1 operation. Then after that I could consider how to make it do more operations. Turning it into a true arithmetic calculator might be a bit much to start with.
