Two-digit prime numbers whose digits add up to 10 are:193773
The only two digit numbers whose digits add up to 17 are 89 and 98. Since 98 is an even number, 89 is prime.
The smallest prime number, of course, is 2. The smallest prime number whose digits add up to 2 is, of course, 2. The next-smallest is 11. It is left as an exercise for the reader to determine whether the other numbers whose digits add up to 2 (e.g. 101, 1001, 10001) are prime.

Prime numbers with hundreds of digits have been found, but there are still more to come that haven't been found yet. It's not possible to add up all the prime numbers, because nobody knows what they all are yet. Since there is no last prime number (this was proved 2000 years ago by Euclid), the sum of all prime numbers is infinite.

2014 ( The sum of the digits = 7, a prime number )
Remember , when starting from the decimal point, and moving to the left, each digit column is named ;- Units, Tens, Hundreds, Thousands, Tens of thousands, 'Hundreds of thousands' and ' millions. Again starting the with decimal point, and moving to the right, each digit colum is named ; 'Tenths,' , Hundredths, 'Thousandths', Ten of Thousandths', Hun dreds of thousandths, & millionths. Note the use of '-ths' in the decimal digits. As an example 1234.567. '1' is thousands '2' is hundreds '3' is tens '4' is units '5' is tenths '6' is hundredths '7' is thousandths. Such a numbers as 1,000,000 is said as 'one million; Conversely such as number as 0.000001 is said as 'one millionth'.
