In game theory, "guess 2 / 3 of the average" is a game where players simultaneously select a real number between 0 and 100, inclusive. The winner of the game is the player(s) who select a number closest to 2 / 3 of the average of numbers chosen by all players.
2 3 = 8 down 3; 3 3 = 27 down 1; 4 3 = 64 down 3; 5 3 = 125 up 1; 6 3 = 216 up 1; 7 3 = 343 down 3; 8 3 = 512 down 1; 9 3 = 729 down 3; 10 3 = 1000 up 1; There are two steps to extracting the cube root from the cube of a two-digit number. For example, extracting the cube root of 29791. Determine the one's place (units) of the two-digit number.
The final digit of a triangular number is 0, 1, 3, 5, 6, or 8, and thus such numbers never end in 2, 4, 7, or 9. A final 3 must be preceded by a 0 or 5; a final 8 must be preceded by a 2 or 7. In base 10, the digital root of a nonzero triangular number is always 1, 3, 6, or 9. Hence, every triangular number is either divisible by three or has a ...

Number Scrabble (also known as Pick15 [1] [2] [3] or 3 to 15 [4]) is a mathematical game where players take turns to select numbers from 1 to 9 without repeating any numbers previously used, and the first player with a sum of exactly 15 using any three of their number selections wins the game.
The best strategy is to use the combined score for a high tile (7,8,9), if possible, otherwise choose the lowest tile. The success rate for this strategy is 7.9855%. [6] Digital – A player's score at the end of the turn is the number obtained by reading the up digits as a decimal number from left to right. For example, if 1, 2, and 5 are left ...
The contestant is shown an incorrect price for a car. Each digit displayed is either one higher or one lower than the correct digit in the price (e.g., an initial 7 is either a 6 or an 8). The contestant adjusts each digit and wins the car if they choose all five digits correctly. If all five digits are wrong, the contestant automatically loses.
the 3 is to the right of the ones place, so it is in the tenths place, and is called the tenths digit; [10] the 4 to the right of the tenths place is in the hundredths place, and is called the hundredths digit. [10] The total value of the number is 1 ten, 0 ones, 3 tenths, and 4 hundredths.
