Let p= 1/2*3/4*5/6*7/8……..*99/100.

Is p bigger than, equal to or less than 0.1 ?

The famous Sofia Kovalevskaya (1850-1891) solved this problem allegedly in no time, when she was only twelve years old.

Please provide your answer without programming and without direct evaluation.

fIGURES CAN'T LIE , BUT LIARS CAN FIGURE

You cannot manipulate approximations the way you did. 

Infinity minus another infinity is not zero , it is just  undefined..

The difference between 2 big  numbers can range from zero to big.
