looks like a binary operator that could also have been interpreted as a
term or unary operator. For instance, if you know that the rand
function has a default argument of 1.0, and you write

    rand + 5;

you may THINK you wrote the same thing as

    rand() + 5;

but in actual fact, you got

    rand(+5);

So put in parentheses to say what you really mean.
