Answer 7

@mathwhiz99 0 is never included in the list of natural numbers instead it is a whole number..

NATURAL NUMBERS : {1, 2,3,4,5.............................................................}

WHOLE NUMBERS : {0,1,2,3,4,5...........................................................}

Answer 8

some include it. i didn't want to generalize. it really just depends on what the teacher prefers. some include 0 as natural. some dont.

Answer 9

Well, I have never heard and studied that..

Answer 10

i, for one, consider 0 to be a whole number too. But, we never know if the teacher's preference would be to include 0 in the natural numbers. It's really controversial.

Answer 11

{N}=1,2,3,..............inf.{sometimes including zero}
{W}=0,1,2,3...........................infi.
{Z or I} = -inf.................-3,-2,-1,0,+1,+2,+3..............+inf.
