[SOLVED] Add/Subtract depending on positive/negative number?


Recommended Posts

Luckily, the way positive and negative numbers works, you can do the following:

 

$a + $b

 

Let's say a is 10 and b is 9, that will yield 19....  Let's say b is -9....

 

10+-9

That would be 1 ;p.

 

Yeah I just noticed that! Thanks
