Today we watched this video about this guy who can do really really hard math problems mentally and he gets them right!! It's really crazy i was kinda second guessing it but i guess it is possible i dont know really but maybe he studies the answers I really don't know. He was also guessing the days people were born like asking them what year they were born, what month they were born, and the date, for example year 1956, april, and the 19th day , now he would sat the day of the week they were born. It's so crazy! He uses these words instead of long numbers like cookie or something like that, to rememer. The last thing he did was mentally cauculate a five digit number like he squared it mentally!
