*speechless*

Have you seen somethings in your academic textbooks which makes you laugh? Well I came across something funny from my Calculus Textbook the other day when I was doing some revision. Well as you know math is really about practicing your sums to get better in solving problems.

Hahaha that was what exactly I was doing the other time and I needed to check my answers with the answers given at the back of the textbook. Would your textbook's answer ever tell you this;

You see it's pretty amazing that your textbook can actually tell you this as an answer (even though in fact this is the actual answer to one of the sums in the book). It's rather funny to see a book cracking a joke to you. My friends couldn't belief it too and when they saw it they laughed at it too...

Well... as the saying goes, never judge a book by its cover...
