1001 1010 1100 they all are
two consecutive 4- digit numbers have a sum of 9173.what are the numbers?
The sum of two numbers is a whole number if both of the numbers are whole numbers, or if the sum of two fractions can be simplified to a whole number.
It is not clear what the question means: there are 31 2-digit numbers that can be expressed as a sum of two squares.
Highest 2-digit number = 99 Highest 1-digit number = 9 Highest possible sum from 2, 2-digit numbers = 198 Highest possible sum from 2, 1-digit numbers = 18
Odd numbers
21
The 3 largest 2 digit prime numbers are 83, 89, and 97. The sum is 269
IN WHOLE NUMBER FIRST DIGIT IS 0 SO THAT WE HAVE TO SUM 1-98 NUMBERS :-SUM OF 1-10 IS 55 SO IN SUM OF EACH 11-20,21-30......THE UNIT DIGIT WILL COME 5 SO FOR THAT WE MULTIPLY 5*9+1+2+3+4+5+6+7+8 AFTER THIS CALCULATION WE GOT 1 AS A UNIT DIGIT NUMBER
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
19, 998.
