Avoid looking like Education Secretary Nicky Morgan who was stumped when asked to do a cube root: https://www.youtube.com/watch?v=x8CV0dfQMdU Note: the starting number needs to be a perfect cube.

Current pricing on the Zenfone 3 Deluxe is here: http://amzn.to/2j5kpl0 No matter how hard you try... accidents can happen to your cell phone. Its interesting to see how a smartphone can hold up against every day abuse. My tests simulate a few years worth of accidental abuse that could happen to any cell phone. The newest phone to fall under my razor is the Asus Zenfone 3 Deluxe. Its interesting how hard phone manufactures will push an all metal design when their phone isn't all metal. The Samsung phone is a metal phone under a glass panel. And we don't call it metal. We call a phone by whatever material is on the exterior. As long as phone manufactures are exaggerating material claims... Ill be here testing phones and calling them out.
