Some finite numbers in a set: the number of digits on your hand, the number of seats on a bus, and the number of people on earth. Some infinite numbers in a set: the number of positive integers and the number of digits in pi.

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.

Your question was a little unclear in two ways: You said "using 3 digits". Are 1 and 2 digit numbers allowed? and If you reorder the numbers in a set, do you count it twice? For instance, if you had already counted the set 101, 102, 103, 104, 105, 106, would you also count 106, 105, 104, 103, 102, 101? If yes to both questions, there are 985,084,775,273,880,000 different sets. If yes to the first question, no to the second, there are 1,368,173,298,991,500 different sets. If no to the first question, yes to the second, there are 522,639,254,696,832,000 different sets. If no to both questions, there are 725,887,853,745,600 different sets. Hope this helped :).

The paint code for a 19 is on the metal VIN plate rivvetted to the slam panel. THere are two sets of numbers, the ones you want are inside an oval on thr right-hand side of the plate. There are four rows of numbers, you need the third row down. There will be two digits, a break, three digits, a break and then three digits. The middle three digits are the paint code.

There are infinitely many possible sets.For example, using 2 numbers,25 + 25, 24 + 26, 23 + 27, ... 1 + 49, 0 + 50, -1 + 51, -2 + 52, ....Then you can look at numbers with 1 digit after the decimal point:24.9 + 25.1, 24.8 + 25.2, and so onNext you can look at numbers with 3 digits, 4 digits, ... , infinitely many digits after the decimal point.Then move to triplets of numbers, sets of 4 numbers, 5, 6, ... infinitely many numbers.

They are totally separate things. Systems of units are standard sets of dimensions in which things are counted and measured. Significant digits are simply accuracy levels in numbers, such as 3.142 compared to 3.1416.

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