In a typical 6/49 game, each player chooses six distinct numbers from a range of 1–49. If the six numbers on a ticket match the numbers drawn by the lottery, the ticket holder is a jackpot winner— regardless of the order of the numbers. The probability of this happening is 1 in 13,983,816. The chance of winning can be demonstrated as ...
Then, round the final result, for example, to the fewest number of significant figures (for multiplication or division) or leftmost last significant digit position (for addition or subtraction) among the inputs in the final calculation. [14] (2.3494 + 1.345) × 1.2 = 3.69 4 4 × 1.2 = 4. 4 3328 ≈ 4.4.
495: the last digit is 5. 6: It is divisible by 2 and by 3. [6] 1,458: 1 + 4 + 5 + 8 = 18, so it is divisible by 3 and the last digit is even, hence the number is divisible by 6. Sum the ones digit, 4 times the 10s digit, 4 times the 100s digit, 4 times the 1000s digit, etc. If the result is divisible by 6, so is the original number.
Perfect number. In number theory, a perfect number is a positive integer that is equal to the sum of its positive proper divisors, that is, divisors excluding the number itself. For instance, 6 has proper divisors 1, 2 and 3, and 1 + 2 + 3 = 6, so 6 is a perfect number. The next perfect number is 28, since 1 + 2 + 4 + 7 + 14 = 28.
To determine the actual value, a decimal point is placed after the first digit of the significand and the result is multiplied by 10 5 to give 1.528535047 × 10 5, or 152,853.5047. In storing such a number, the base (10) need not be stored, since it will be the same for the entire range of supported numbers, and can thus be inferred.
The digit sum of 2946, for example is 2 + 9 + 4 + 6 = 21. Since 21 = 2946 − 325 × 9, the effect of taking the digit sum of 2946 is to "cast out" 325 lots of 9 from it. If the digit 9 is ignored when summing the digits, the effect is to "cast out" one more 9 to give the result 12.
Therefore, six-number games generally offer a higher top prize. A straight six-number game is different from "two-drum" games such as Powerball, Cash4Life, Lucky for Life, and Mega Millions. While these games also draw six numbers, five are from one set, while a sixth is drawn from a second pool. These "5+1" games also require all six numbers ...
The Mental Calculation World Cup 2016 was held from 23 to 25 September 2016, in Bielefeld Germany. 31 mental calculators from 16 countries participated. The World Cup involved the following 5 main contests: Adding ten 10-digit numbers, 7 minutes. Winner: Yuki Kimura (Japan) Multiplying two 8-digit numbers, 10 minutes.
