ok here is one story about how math is ruining my mood !
It was after midnight ... I was in charge of finalizing our project's proposal ... I was so damn tired and sleepy.... I barely could open my eyes...
I finished my job, then I wanted to forward the document to my group...
I clicked send... then this stupid nerve hitting message appeared ...
math !!! I thought it's only captcha ... why is it math !
it was so frustrating ... trying to use my mind at that state... and u can notice from the screen shot that I needed more than one trial -_-
Now what was this for ? does google want us to hate them?!
nope... I guess!
This feature is called Mail Goggles ( one of Labs interesting features) which u can enable from settings menu.
This is the description of this feature :
