lol Genius, let's just assume his question is "How can I perform multiple calculations with $calc?"
The answer is surprisingly found in the mIRC help file! Go figure ....

Returns the result of the specified operations. This identifiers allows you to perform multiple operations easily. For example:
$calc(3.14159 * (2 ^ %x % 3) - ($ticks / (10000 + 1)))
