I need a way to ask wolfram for only certain type numbers within a range: (I know what the answers should be -- my question is how do I ask the question to Wolfram, to get the correct answer)

Examples

-10,10 only whole numbers

-10,10 only counting numbers

-10,10 only natural numbers

-10,10 only integers

-10,10 only primes

i.e. how can I specify a range and have wolfram only return a certain type of number in response?

W|A accepts Mathematica code and as your question is mathematical Mathematica code is worth trying first.

Its functions take the form Function[parameters] so you try your luck with

Prime Numbers [1,5]

and you get some output.

You check the 'Input Interpretation' pod. This says W|A has interpreted your input as Primes between 1 and 5 and you are satisfied your question has been interpreted correctly,

The 'values' pod in the output has the answer 2,3,5

If it had not worked you could have delved into the Mathematica documentation at:-

http://reference.wolfram.com/mathematic ... atica.html

using its search box.

Prime Numbers [-10,10]

and it responds

2 | 3 | 5 | 7 (4 primes)

Does that answer your question?
