429 PointsMultiplying Two variables
I don't understand what I am doing wrong, I have multiplied it, I used the echo function and I don't have any spelling error.
<?php
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
echo $integerOne * $floatOne;
$integerOne += 5;
var_dump ($integerOne);
$integerTwo -= 1;
var_dump ($integerTwo);
echo $integerOne * $floatOne;
?>

<?php
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
$integerOne += 5;
$integerTwo -= 1;
echo $integerOne * $floatOne;
?>

Remove the var_dumps and the first echo statement

429 PointsI have just done that and this is the error that it is giving me. "Bummer: Are you sure you multiplied $integerOne by $floatOne? This should be the same as 6*1.5 which equals 9."
