Because your expression is e minus (lots of unary minuses) 5. There is no unary plus operator.

Mathematically speaking it's wrong as it's not allowed to have two operators next to each other.
Why is it allowed and why aren't multiple + operators allowed? Because it's PureBasic.
Simple as that.

The expression is actually evaluated as (shortened here) e-(-(-(-(-(-5))))) which is perfectly valid, even in mathematics.

...of course I was talking about PB's implementation.
It doesn't matter how it's interpreted, the notation is still wrong.
And I'm not saying it bothers me (as I would never write it like that because it simply doesn't make sense to do so).
