Well what, quite well. For example, the reinstallation of Windows is estimated somewhere in 2k. For a day, without stressing especially, you can put 3 screws. For 2 weekends - 6, for a month - 24. In total, for a year such work brings up to half the money, and in 9 years you can earn for an apartment in Moscow.

Mathematicians shouldn’t be economists. Apparently everything was calculated correctly, but in reality this is impossible.
