What are 2 mathematical things about the number 9?
The number nine is a composite number (3 x 3 = 9) and it is a square number (32 = 9). It is a divisor of any number that has digits having the sum of nine or a multiple of 9 (For example, the digits in 367,218 add up to 27, which is a multiple of 9, and the digits in 27 also add up to 9)
What 3 digit numbers are not divisible by nine?
Any number whose digits do not add up to 9, 18 or 27. There are 800 of them!
Is 210 divisible to 3?
Since the digits of 210 add up to 3, and that is divisible by 3 then 210 is divisible by 3. This works for 3, 9, and 27.
What do the digits of each multiple of 9 add up to?
They also add up to a multiple of 9.
How many counting numbers have four distinct nonzero digits such that the sum of the four digits is 11?
To find how many counting numbers have four distinct nonzero digits that sum up to 11, we first identify all combinations of four distinct digits (from 1 to 9) that meet this criterion. The possible combinations of digits that add up to 11 are limited, and we can use combinatorial methods to list them. After identifying valid sets, we can calculate the permutations for each set (since the order of digits matters) to get the total count. Upon calculating, we find there are 24 valid combinations yielding 576 distinct numbers.
Write down four odd digits that will add up to 19?
There are no four odd numbers that will add up to nineteen.
A three digit number whose digits add up to 900?
Three digits can't possibly add up to 900. The largest possible sum of 3 digits is (9 + 9 + 9) = 27.
What Four odd digits will add up to 19?
3, 7 and 9. 4 odd digits that add up to 19 would be 9, 9, 0.5, 0.5

You are a three-digit number and a common multiple of 27 and 11 The sum of your digits is 10 What number are you?
Common three-digit multiples of 27 and 11 are 297, 594 and 891. None of their digits add up to 10.
What 3 digit numbers are not divisible by nine?
Any number whose digits do not add up to 9, 18 or 27. There are 800 of them!
What are four consecutive numbers that add up to 102?
24, 25, 26, 27 (next to each other and add up to 102)
Is 210 divisible to 3?
Since the digits of 210 add up to 3, and that is divisible by 3 then 210 is divisible by 3. This works for 3, 9, and 27.
What do the digits of each multiple of 9 add up to?
They also add up to a multiple of 9.
Are all numbers divisible by 9 divisible by 3?
A number is divisible by 9 if all the digits add up to 9 or are a factor of. IF the digits add up to 9 (or a factor of 9), they will automatically be a factor of 3.Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.
