In a number (integer) the last digit on the right is "how many units". Then next to the left is "how many tens". The next is "how many hundreds". Notice the progression 1 to 10 to 100. To the right of the decimal point, for numbers smaller than 1, in sequence you have 1/10, 1/100, 1/100 etc. 52 means 5 tens and 2 units. 25 means 2 tens and 5 units.
Move the decimal point 9 positions to the right. Fill out missing digits with zeros.
If the digits may not be repeated, there are 6x5x4x3x2x1 = 720 numbers, If digits can be repeated, the answer is 6x6x6x6x6x6 = 46,656 numbers If zero is ong the available digits but is excluded from the first place. 5x6x6x6x6x6=38,880 numbers
The general rule is, with X symbols in Y positions, you can form XY combinations.For example, with 10 digits (0–9) in two positions you can form 102=10×10=100 combinations (00­­­–99).With 6 digits in three positions, you can form 63=6×6×6=216 combinations.
10 digits are numbers in the billions.
There are 5 numbers of 1 digit, 25 numbers of 2 digits, and 75 numbers of 3 digits. This makes 105 numbers in all.
Nine digits, four positions becomes 94 or 6561.

0.175mg is more. As long as the numbers are both positive and you are careful about comparing digits in the same relative digital locations for both numbers, [positions of zeros count] you can compare such numbers as you would whole numbers. Of course, don't forget to include digits to the left of the decimal point in the event that not both numbers are less than 1.
10 digits are numbers in the billions.
There are 5 numbers of 1 digit, 25 numbers of 2 digits, and 75 numbers of 3 digits. This makes 105 numbers in all.
there are 899 whole numbers that have three digits.
You need to add all the digits at odd positions, and subtract all the digits at even positions (counting positions from the right). For example, for the number 143, you calculate: +3 + 1 - 4 = 0.If you get a multiple of 11 (including 0), as in the example above, you have a multiple of 11.

Armstrong numbers are the sum of their own digits to the power of the number of digits.
