1,006 PointsWon'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: ?>

Treehouse Moderator 38,105 PointsHi Ross Christie So when it says to add 5 to integerOne they donβt 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!
