I love trying to memorise these cool tricks... this one requires a lot of memory skill but is worth the effort!

Math. Love it or hate it, everyone must do it at some point in their lives.  Some of us revel in numbers and equations and have a passion for math.  This Instructable is for you, oh math lovers of the world.</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.instructables.com/id/Take-Cube-Roots-of-6-Digit-Numbers-Mentally/"><DIV>
This Instructable describes mental cube-root extraction: a cool math trick you can do to amuse and amaze your friends, and score some mean cubicle-cred with your fellow geeks.  I can accept no responsibility for the social implications of using this skill (but then, as a geek, you probably already treat social implications of your geekiness with abandon, so it's all good).</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/19BE3B0A-D476-4F94-833D-2D8EA29228D2/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
