Challenge Task 2 of 3

Add 5 to $integerOne. Subtract 1 from $integerTwo.

You'll need to keep in your original code otherwise your mathematical variable updates won't work. For example, in your answer, your defining a variable then taking that same variable which hasn't been assigned to anything yet and adding it to an integer. Thus you should first declare the variable, then feel free to make updates after. Such as the example below.

$integerOne = 1;
$integerTwo = 2;

$integerOne += 5;
$integerTwo -= 1;

Challenge Task 3 of 3

Create a New Float Variable named $floatOne with a value of 1.5. Without changing the value of $integerOne or $floatOne, multiply $integerOne by $floatOne and display the results.

$integerOne = 1; $integerTwo = 2;

$integerOne += 5; $integerTwo -= 1;

$floatOne = 1.5;

$total = $integerOne x $floatOne; echo $total;

What did I wrong

you multiply by using *, not x.
