Won't add or subtract

It won't add to make up to 6 or 1 respectively. When I have this it say's it integerOne needs to be 1 but when I don't it say's it needs to be changed. I don't understand and I'm overwhelmed for some reason.

Line 1: <?php Line 2: Line 3: //Place your code below this comment Line 4: $integerOne = 1 + 5; Line 5: $integerTwo = 2 - 1; Line 6: $floatOne = 1.5; Line 7: ?>

Hi Ross Christie So when it says to add 5 to integerOne they don’t want you to do it in the declaration. They want you to do it on another line.

Something like

$integerOne = $integerOne + 5.

The reason is in real code the tasks are not this simple. You might not know the value of integerOne. Most likely it will be a dynamic value passed into the function. You just know you need to add 5 to what ever the current value is.

Hope this helps and keep learning!

Thank you, it did! Doing PHP Basics straight after doing CSS Basics is really overwhelming my head. And my deadline is tomorrow
