ignore + and -

[RON_ron]

How can I ignore - when doing claculations?

 

e.g.

150 - 50 = 100

150 - 225 = -75 // I WANT to display only 75 and ignore the - sign

I assume you meant that you only want to "ignore" the negative by just echoing  75.  Assuming that's the case, then convert  the negative number  to a positive and echo that value:

 

$val = 150 - 225;
$val = abs($val);
echo $val;

 

The abs function converts a positive to a negative.  See the following:
