What is the sum of greatest 5 digit number?
The greatest 5-digit number is 99,999. The smallest 5-digit number is 10,000. Their sum is 99,999 + 10,000 = 1,09,999.
What is the sum of the first 100 numbers?
5050
Therefore, the sum of first 100 natural numbers = 5050.
How do you find the sum of a three digit number?
The count is 450 such numbers (half of all 900 three-digit numbers). The average of those numbers is 549 (midpoint between 100 and 998). The sum is the count x average = 450 x 549 = 247050.
What is sum of greatest 6 digit and smallest 7 digit number?
For the successor of the greatest 6-digit number, we have to add 1 to the greatest 6-digit number. Smallest 7-digit number= 1 + Greatest 6-digit number = 1 + 9,99,999 = 10,00,000.
What is the greatest number of 6 digit?
999999
As we know the greatest 6-digit number is 999999.
How to find the sum of all 3 digit numbers?
Let us see how to find the sum of all 3 digit numbers divisible by 6 in the following steps. The first 3 digit number divisible by 6 is 102. After 102, to find the next 3 digit number divisible by 6, we have to add 6 to 102. So the second 3 digit number divisible by 6 is 108.
What is the sum of digits of adding 8 to 7?
Adding 8 to 7 results in a sum of digits of 6, and so on down to adding 8 to 1 which gives 9. Even this fits into the rule in the sense that if 1 were reduce by 1 the result would be 0 which is equivalent to 9 modulo 9. Likewise adding 7 to a digit reduces it by 3 and adds 1 to the digit in the next place, a net reduction in the sum of digits of 2.
What happens when you add 7 to a number?
Likewise adding 7 to a digit reduces it by 3 and adds 1 to the digit in the next place, a net reduction in the sum of digits of 2. Thus when 7 is added to 7 the sum of digits is reduced to 5. When 7 is added to 5 the sum of digits is reduced to 3. When 7 is added to 3 the sum of digits is reduced to 1.
How are the digits of multiples of nine sum?
The Sum of Digits for Multiples of Numbers It is well known that the digits of multiples of nine sum to nine; i.e., 9→9, 18→1+8=9, 27→2+7=9,…, 99→9+9=18→1+8=9, 108→1+0+8=9, etc. Less well known is that the sum of digits of multiples of other numbers have simple patterns although not so simple as the case of nine.
