The number 2464 fulfils the requirements.
Not necessarily. Consider 444. The digits are not different. The first and second digits are not multiples of 3 The first digit is not greater than the second digit. In spite of all that, 444 is a 3-digit number
There are the digits 1 through 9 for the first digit. Then, we have 0 through 9 for the second digit - excluding the first digit. For the third digit, we have 0 through 9 excluding the two previous digits
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
Assuming that 2356 is a different number to 2365, then: 1st digit can be one of four digits (2356) For each of these 4 first digits, there are 3 of those digits, plus the zero, meaning 4 possible digits for the 2nd digit For each of those first two digits, there is a choice of 3 digits for the 3rd digit For each of those first 3 digits, there is a choice of 2 digits for the 4tj digit. Thus there are 4 x 4 x 3 x 2 = 96 different possible 4 digit numbers that do not stat with 0 FM the digits 02356.
1348.
The first occurrence of the digit 0 in the digits of pi is at the 32nd decimal place.
The first digit would have to be 1, the remaining digits, zero.

Since there is no whole part, compare the digits after the decimal point one by one (first digit with first digit, second digit with second digit, etc.), until you find two digits that are different.
