    Paradizingmania:

    You should read the perlop documentation, it describes what all the operators are. Having said that:

    • $a <= $b means "$a is less than or equal to $b"
    • $total += $num means the same as $total = $total + $num
    • $count++ means the same as $count = $count+1

    ...roboticus

    When your only tool is a hammer, all problems look like your thumb.

    Hi Paradizingmania,

    Roboticus has given you the answers to your questions, but I should stress these questions relate to really basic Perl operators, and that you should absolutely take a serious look at the documentation pointed by him in his answer (perlop). Also take a look at the documentation pointed out by toolic, especially perlintro.
