Well, how have you tried to handle `5 * -5` in your code? Right now, `5 * -5` gives me `0`, which makes no sense.

> If 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign.

Right now, `5 * + 5` also doesn’t work. It returns `5` but should return `10`.
