This video will accurately guess your age and number!!!!

It is just a tricky maths.. for your understanding let me explain you how it works..
For example if i ask you to substract 2021( current year ) or 2020 (if your birthday hasn't came yet) - your year of birth = your age. Its simple but in this video to make it tricky 1770 & 1771 is used instead of 2021 or 2020.
