Take 4004 and subtract half of it, add the remaining one-third, then subtract one-quarter of the sum, and then add one-fifth of the difference. Finally, subtract one-half of the sum. What's the final result?

Take 4004 and subtract half of it, add the remaining one-third, then subtract one-quarter of the sum, and then add one-fifth of the difference. Finally, subtract one-half of the sum. What's the final result?

4004-4004/2=2002
2002+2002/3=8008/3
8008/3-8008/12=2002
2002+2002/5=12012/5

The law is obvious, and the result is 2002
