in reply to Operators: arithmetic and otherwise

The second variable $a=3 should be $b=3 I believe:

`$a=2;`__$b=3;__print $a+$b #arithmetic operator prints 5 print $a.$b #string operator prints 2 plus the three or 23 print $a*$b #arithmetic operator prints 6 print $a x $b #string operators prints $a $b times or 2 three times. i +e 222
