The number of combinations you can make with the digits 1234567890 depends on how many digits you want to use and whether repetition is allowed. If you use all 10 digits without repetition, there are 10! (10 factorial) combinations, which equals 3,628,800. If you are choosing a specific number of digits (for example, 3), the number of combinations would be calculated using permutations or combinations based on the rules you set.
it is like when you have a number you use that number to make it bigger
To estimate the number of digits in a tetration you have to use the modulus value.
If you can use decimals, then the smallest number would be 0.8765321. But if you can't use decimals, then it would be 10235678.
If you have to use all four digits - 1349. If you can use them in a sum 9-4-3-1 = 1
The number 202.45 has five significant digits.
If you have to use all five digits... 20356
The sum is 22 times the sum of the three digits.
543,210. If you can use them all multiple times, then it is 555,555.
RoundUp function returns a number rounded up to a specified number of digits. (Rounds away from 0.)Syntax: RoundUp( number, digits )number = number to round updigits = number of digits to round the number up to
Other than its general uses in math classes. The most important use is encryption. When you have information that you are encrypting you embed into a "very" large number. (the bigger the number the better the encryption) Then the key to unlocking that encryption is the prime factors of that "very" large number. By "very" large number I mean numbers with more than 1,000,000,000 digits since the largest "known" prime number is around 50,000,000 digits
The number system we commonly used, known as the decimal system, has 10 digits (0 to 9). It is possible to use other number systems, with a different number of digits. Any numbering system based on the same principle (the principle of place-value) must use 2 or more digits.
