All numbers are made with digits and there is no limit on how big they can be. So there is no greatest number.
The significant digits in a number can be arbitrarily small or large in number, according to the method of creating them.Numbers that can have an infinite number of possible significant digits are called transcendental numbers.
§ In comparing two whole numbers, the one with the most digits is always the greater number. § In decimals the number with the greatest number of digits is not always the greatest.
The greatest possible number is 888... (repeating).
Because in our system of numbers 100,000 is greater than 99,999.
no, it matters with the number not digits
To be honest, numbers go on and on. (they never stop). So it's infinite. The least number would be Negative ( - ) About zillions of digits of numbers.
The positional place values of digits in negative numbers are in ascending order from least to greatest as for example in the number -987 the least value digit is 9 and the greatest value digit is 7 because -900 < -80 < -7 The positional place values of digits in positive numbers are in descending order from greatest to least as for example in the number 987 the least value digit is 7 and the greatest value digit is 9 because 900 > 80 > 7
The greatest 4-digit number with no repeated digits is... 9876
Digits is how many numbers you have in a number. If you have the number 4 it has one digit if you have the number 20 it has two digits and if you have the number 558 it has three digits. So basically in the number 1085 it has 4 digits because there is 4 numbers in it, the numbers are 1,0,8 and 5. Hoped you understand.
