Infinity.

That means the number itself is divisible by three. the sum of the digits in 144, for example, is 9. 144 divided by 3 is 48. The sum of the digits in 21 is 3. 21 divided by 3 is 7.If the number is an even number and the sum of the digits is divisible by 3, the number is also divisible by 6. 144 is even and the sum of the digits is divisible by 3, so 144 is also divisible by 6. 144/6 = 24. And finally, if the sum is divisible by 9, the number itself is also divisible by 9. 27 is an example of this.

The number is 16.

9046. 20 ÷ 11 = 1.81... With the 81 repeating forever. So the sum of the first 2011 digits is the first digit plus the next 2010 digits which are "81" repeated 1005 times. Sum = 1 + (8 + 1) x 1005 = 9046

The answer depends on how many decimal places are in the summands.

2025.

It is 135.

int Sum( int digits ) { if(digits < 10) return digits; return digits%10 + Sum(digits/10); }

13.2 3.7 has one digit after the decimal and 9.495 has three digits after the decimal You take the least number, which is one. The final answer has one digit after the decimal.

the sum of my digits is 6? answer=60

Add the digits together. The sum of the digits of 23 is 5.

0.0304

The sum of the digits is also a multiple of 9. And, if the sum of the digits is too large, you can sum those digits and keep going.

first read nd write all individual digits then goto sum funtion use by adding all individual digits..

Count the numbers of digits after the decimal points (DP) in the two numbers.Add these numbers together.Calculate the product, including any trailing 0s.Place the DP so that the number of digits after the DP is the same as the sum of the digits after the DP (step 2).Thus, for 15.38 * 0.0045The first number has 2 digits after the DP, the second has 4, so sum of digits after DP is 2+4 = 6.1538*0045 = 69210.The answer must have 6 digits after the DP so you need to insert a 0 after the DP to make it .069210 which can then be simplified to .06921

Add the digits together. The sum of the digits of 23 is 5.

-- If you accept 4-digit numbers with 'zero' as the first digit, thenthere are 24 possibilities, and their sum is 119,988 .-- If the first digit can't be a 'zero', then there are 18 possibilities,and their sum is 115,992 .Note: I didn't repeat any digits.-- If you allow repeated digits, and accept leading zeros, then there are 256 possibilities,and their sum is 1,279,872.-- If you allow repeated digits but not leading zeros, then there are only 192 possibilities,and their sum is 1,247,904.

8 is the same as the sum of the digits of its cube, 512.

1 + 1 = 2 The sum of the digits is therefore 2.
