The nines' complement of a decimal digit is the number that must be added to it to produce 9; the nines' complement of 3 is 6, the nines' complement of 7 is 2, and so on, see table. To form the nines' complement of a larger number, each digit is replaced by its nines' complement. Consider the following subtraction problem:
The game can be played by 2 players, or 4 players split into two teams. Cuarenta is the national card game of Ecuador and even has official tournaments. The score is kept with two kinds of chips, the two-point tantos (points) and the ten-point perros . When a standard 52 card pack is used, the 8s, 9s and 10s can be used to keep the score.
The jacks, queens and kings may be removed instead of 8s, 9s and 10s. No cards are removed. Each player may be dealt nine cards and attempt to meld 10. Three players can play this game with eight cards being dealt and attempt to meld nine. Four players can play with seven cards dealt and attempt to meld eight.
The extended Midy's theorem [2] states that if the repeating portion of the decimal expansion of a/p is divided into k-digit numbers, then their sum is a multiple of 10 k − 1. For example, 1 19 = 0. 052631578947368421 ¯ {\displaystyle {\frac {1}{19}}=0.{\overline {052631578947368421}}}
The 9's complement of any one-digit decimal number d is 9-d. So the 9's complement of 4 is 5 and the 9's complement of 9 is 0. Similarly, the 11's complement of 3 is 8. In a decimal machine with n dials the 9's complement of a number A is: = and therefore the 9's complement of (A-B) is:
