First ask a question-under what circumstances does 7 plus 8 equal 16?
This is not a sketch of Zhao Benshan fooling Fan Wei, but a serious discussion about mathematics. The correct answer is-in decimal mathematics, 7 plus 8 equals 16!
There are ten basic numerical symbols in commonly used decimal mathematics: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. (attention! There is no "ten" in the decimal basic number symbol. Ten is composed of 1 and 0, which means that every decimal number has a mantissa of 0. )
But in decimal mathematics, there are nine basic numerical symbols, namely 0, 1, 2, 3, 4, 5, 6, 7 and 8. (attention! There is no "nine" in the basic number symbol of nine, and nine is equal to 10, which means the mantissa is 0. )
Then the natural decimal sequence is: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,1,12, 13,/.
The decimal natural number sequence is: 1, 2, 3, 4, 5, 6, 7, 8, 10,1,12, 13,/kloc.
So in nine-digit mathematics, 7+8= 16.
It is said that the nine-digit mathematics mentioned in the book "Related Essays" on the Landlord is of course related to the traditional geomantic omen in China. Ancient earth masters want to study traditional metaphysics, and the gossip in the Nine Palaces never leaves their mouths, which sounds very mysterious. But from the "number" point of view, they ...
