There is no solution to this problem.
If each digit can be used once only then we have 5 odd numbered digits (1,3,5,7,9) and 4 even numbered digits (2,4,6,8).
To create the two numbers that are added together requires the following combinations of digits.
5 Odd & 1 Even ....when added these will generate 2 Even digits & 1 Odd digit but the remaining digits are 3 Even.
4 Odd & 2 Even. These will generate 3 Even digits OR 1 Even digit & 2 Odd digits but the remaining digits are 1 Odd & 2 Even.
3 Odd & 3 Even. These generate 3 Odd digits OR 2 Even & 1 Odd digits but the remaining digits are 2 Odd & 1 Even.
2 Odd & 4 Even. These generate 3 Even digits OR 2 Odd & 1 Even digits but the remaining digits are 3 Odd & no Even.
In the numbers 1-9 each number has 1 digit and there are 9 of them, so that's 9.In 10-99 each number has 2 digits, and there are 90 of them: 2x90 = 180There are 900 three digit numbers [100 through 999]: 2700 digits.There are 9000 four digit numbers: 36000 digits.90,000 numbers with five digits: 450,000 digits.900,000 numbers with six digits: 5,400,000 digits.Then 1 number with seven digits: 7 digits.Add them up and you have 5,888,896 digits.
I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24
No. Natural numbers are positive (or zero) whole numbers - without digits after the decimal point.
∞ \ Infinite
Without repeating digits (not digets!) and without leading 0s, 600 of them.
It is possible to create a 3-digit number, without repeated digits so the probability is 1.
To show very large or very small numbers, without writing out all the digits. To make it easy to compare such numbers, without having to count all the digits.
Almost got me on this one. 20 numbers but 29 digits
It is 987654321.

90. all the numbers from 10 through 99
There are 17 such numbers.
No, because a quotient requires two numbers. Given the two numbers it is quite easy to work out the number of digits in the quotient.
