the largest number - the smallest number
There is no such thing. As soon as you find the "largest number" you could just add one and it would be bigger. Again and again forever.
take the largest number in the sample and subtract the smallest number that is the range
To find the largest number: Assume (temporarily) that the first number is the largest number. You might call this the "largest number found so far". Then, for each number after the first one, compare the number with the largest number found so far. If the new number in the list is larger, call that one the "largest number found so far". Repeat for each number. After processing all the numbers, the "largest number found so far" will simply be the largest number.For example, if your list is (5, 2, 8, -1), you start assuming that 5 (the first number in the list) is the largest number. You compare with 2 - "5" is still the largest number, since 2 is smaller. When you compare with 8, you find that 8 is larger, so you replace your "largest number" with 8. "-1" is smaller, so nothing changes. Since we processed the entire list, the largest number is now 8.You can do the same - mutatis mutandis - to find the smallest number.
grass and vegatation
No.
Subtract the smallest number from the largest number and you will get the distance from the smallest number to the largest number. That is the range. Ex: {-2 -4 -6 3 6 7 12} Smallest number is -6, largest number is 12. 12- (-6) = 12 + 6 = 18. The distance from the smallest number to the largest is 16

No, numbers go on and on forever.
by looking in internet
It has been proven that there is no largest prime number. You can find a list of the largest KNOWN prime numbers here: http://en.wikipedia.org/wiki/Largest_known_prime_number
