brackets wont work

Hi,
I'have tried evaluate simple function:
echo $m->evaluate('-1*(5+2)');
but got error:
Undefined offset: -1
line 385
function last($n=1) {
return $this->stack[$this->count-$n];
}

without brackets everything is ok.
Has anyone tried this with brackets?

Hi, yes I get the same error.
I tried this: 2*(y+y*3)

And I got this warning:
Undefined offset: -1 [APP\Vendor\evalmath.php, line 384]

However, I get the correct answer returned!

Oh, I forgot to mention I have prepared evalmath by giving y a value, like 'y=12' for example.

evalmath.e('y=12');
$res = evalmath.e('2*(y+y*3)');

Gives me the warning:
Undefined offset: -1 [APP\Vendor\evalmath.php, line 384]

But $res contains the correct answer.

The people at stackoverflow as always has the solution: :)
