what would cause the syntax error?

what would cause a syntax error when adding $a = $a + 5; / var_dump($a);
I followed the steps of the video yet still come across the same problem.

this is my code :

$a = 5;
$b = 10;

  var_dump($a * $b); 
  var_dump($a / $b); 

$a = $a + 1;
  var_dump($a); /* 5 + 1 = 6*/

$a ++;
var_dump($a); /* 6 + 1 = 7*/

$a --;
var_dump($a); /* 7 - 1 = 6*/


$a = $a + 5;  ------ this is where it says I have an error.

fixed code formatting

Assuming you don't have have anything after the semicolon in $a = $a +5; in your actual code it doesn't look like anything is wrong.

I ran your code without any errors.
