How Many Grudges are in the Great Book of Grudges?

How many Grudges are in the Great Book of Grudges? Well today I am attempting to answer the impossible question, a question that in itself is probably a grudge but I do not care for science we all must know. If I messed up at any math please let me know I point it out in the video but I am no mathematician and easily could have messed up at some part so if you think I did please let me know. But please enjoy.
