Okay, math was never my subject, but I'm trying to figure out how to add and subtract integers on this PHP quiz I'm doing. I'm also trying to figure out how to post a picture on here as I did take a screenshot.
This question will be a lot easier to understand if I can get a picture on here.
Thanks, a lot!

<?php
//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
var_dump ($integerOne + 5);
var_dump ($integerTwo -1);
?>
As far as your question goes the challenge expects you to update the values. var_dump will only display them. Here you can use either of the following
<?php
//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
$integerOne = $integerOne + 5;
$integerTwo = $integerTwo - 1;
?>
or
<?php
//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
$integerOne += 5;
$integerTwo -= 1;
?>

3,928 PointsThanks, Kris!
I've got a few things going on for the next several hours but I'll try and get it up here as soon as I can.
Gracias

3,928 PointsOkay, here's the question:
Add 5 to $integerOne. Subtract 1 from $integerTwo.
And here's the code:
<?php
//Place your code below this comment $integerOne = 1; $integerTwo = 2; $floatOne = 1.5; var_dump ($integerOne + 5); var_dump ($integerTwo -1); ?>

3,928 PointsLet me know if that's clear enough.

54,967 PointsScreenshots are difficult to work with. One of the preferred means of sharing code is to copy/paste your code and format it using markdown. See the Markdown Cheatsheet link at the bottom for how to do so.
