Alarming Discovery about the Understanding Mathematics Textbook - Corrupt Message Embedded in every page.

I personally carried out a research on this text book and discovered this message is on every page of all the text book series (primary 1-6)

I read a post from someone saying the aim of this devilish message is to stop piracy. How stupid!


Please re tweet until every school stops using this textbook. If piracy should be stopped, it could be done with the use of more user friendly words.
