Challenge Help

hello i ma facing an error in my answer. i have been trying to solve it and watched the videos again and again but can't figure out my mistakes. can someone please help me out.

index.php
```<?php

//Place your code below this comment
\$integerOne = 1;
\$integerTwo = 2;
\$floatOne = 1.5;
var_dump ( \$integerOne );
var_dump ( 1);
var_dump ( \$integerOne + 5);
var_dump ( \$integerTwo );
var_dump ( 2);
var_dump ( \$integerTwo - 1);
?>
```

Remove the var_dumps and check your answer. If you still have an error, post again.

This is the out from my console:

\$integerOne = 1;

< 1

\$integerTwo = 2; < 2

\$floatOne = 1.5; < 1.5

\$integerOne +=5;

< 6

\$integerTwo -=1; < 1

I had the same issue at first. The problem is that you need to actually assign the arithmetic operation to the variable you're trying to alter. Here is the correct solution:

```<?php

\$integerOne = 1;
\$integerTwo = 2;
\$floatOne = 1.5;

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

// Or you can use the shorthand version of the same thing:

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

?>
```

And, of course, if you wanted to display this to the console, you could do the same with `var_dump()`:

```<?php

\$integerOne = 1;
\$integerTwo = 2;
\$floatOne = 1.5;

var_dump( \$integerOne = \$integerOne + 5 );
var_dump( \$integerTwo = \$integerTwo - 1 );

// Again, here is the shorthand:

var_dump( \$integerOne += 5 );
var_dump( \$integerTwo -= 1 );

?>
```

Hope that helps!
