This is a sequel to my post "An actual good calculator." This one has a better prompt, actually ignores spaces, has more possible operations, and a lot more. :D

For those of you that haven't seen the old post, the point of the first "An actual good calculator" was a calculator where you could simply input your expression instead of "Please enter a number" "Please enter a number" "Please enter an operation". It could handle multiple operations at once, followed order of operations, and did NOT use eval() or similar functions.

and yes this is a repost of the "actual good calculator" but it's better.

Enjoy!
