[SOLVED] multiplying numbers in php

[jbrill]

so lets say i have $a (a number) and $b(another number)

 

to add them i do this: $c = ($a+$b) then echo $c

 

but what do i do when it comes to multiplying those two variables?

[Caesar]

<?php

$x = ($a * $b) +2;

?>

 

You mean, like that?

[jbrill]

what does the +2 do?

[teng84]

<?php

$x = ($a * $b) +2;

?>

 

You mean, like that?

 

$x = ($a * $b);

 

the question is not clear

[Caesar]

what does the +2 do?

 

Just showing you that you can add, multiply...pretty much anything you would do with numbers....just using variables.
