What I'm doing wrong?

here is my code: $integerOne = 1; $integerTwo = 2; $integerOne += 5; $integerTwo -= 1; $floatOne = 1.5; echo $integerOne; echo $integerTwo; echo $integerOne * $floatOne;


$integerOne = 1;
$integerTwo = 2;
$integerOne += 5;
$integerTwo -= 1;
$floatOne = 1.5;
echo $integerOne;
echo $integerTwo;
echo $integerOne * $floatOne;

I think you just need to remove the echo $integerOne; echo $integerTwo; And then it works.
