20. Exponential function, chess legend and Indian paratha 🇮🇳

Chess is a very popular game that originated in India, and the word chess itself means king. Legend has it that Indian chess wanted to reward the man who invented chess, but a mathematical problem arose there. Namely, the man asked the chessman to put one grain of grain on the first square, two on the second square, four on the third, eight on the fourth, and then 16, 32, 64 and so on, so that the 64th square should be placed
eighteen quadrillion
four hundred and forty six trillion
seven hundred and forty four trillion
seventy three billion
seven hundred and nine million
five hundred and fifty one thousand six hundred and fifteen
18 446 744 073 709 551 615,
that is, 2⁶⁴ grains of grain. A large number is obtained due to rapid exponential growth. That quantity of grain is so great that not all the grain in India, or even much beyond that, would meet that demand. There would be virtually no grain left for India to use to make flour for many different dishes. One of the most popular is paratha, a thin bread made from wheat flour, salt, water, oil and served with pickles, curry, eggs or meat.
