This is a mental arithmatic question really, but what is the fastest way you have found to multiply two numbers in your head?(adsbygoogle = window.adsbygoogle || []).push({});

How many steps does it take you and what shortcuts do you use?

I apologise if this is the wrong forum.

Examples:

33x24

123x321

9999x6666

etc..
