If you're asking for 4 digit numbers where all four digits are odd, then the lowest number possible is 1111, and the highest is 9999. You only have 5 digits to work with. The answer is: 54 - 53 = 625 - 125 = 500.Subtract the 5 cubed for the numbers less than 1111, which are not four digits.
To assess the number of significant digits in a number, you first have to find the greatest non-zero digit. In this case it is the first five which represent 500. The next step is to simply count how many digits there are after this number. In this case, there are 4 more digits. Thus the number 500.95 has been given to 5 significant digits.
74.6, to 3 significant digits.

500 000, there is 6 digits!
The answer is 498 digits (you're not suppose to count 1 and 500) if this question was intended to ask "how many numbers are there between 1 and 500?"
1 digit number: only 1 number 2 digits number: 18 numbers 3 digits number: 76 So there are 95 numbers containing 9.

Round up to the greater thousand if:the last three digits of the number are greater than 500, orthe last three digits of the number are 500 and the greater thousand is even.Round down to the smaller thousand if:the last three digits of the number are less than 500, orthe last three digits of the number are 500 and the lesser thousand is even.Many schools teach that 500 should always be rounded up. This is a simpler rule but is wrong since such rounding introduces a bias in the results.
