N or the set of the natural numbers are the counting numbers you would use to count with (1,2,3,4,5,...).
\n" ); document.write( "W or the set of whole numbers are the same as natural numbers but you also include 0 (0,1,2,3,4,5,...).
\n" ); document.write( "Z or the set of integers are the set of natural numbers, together with zero and their negative counterparts and include (...-5,-4,-3,-2,-1,0,1,2,3,4,5,...).
\n" ); document.write( "Q is the set of rational numbers that can be described as the ratio between two integers (examples are 1/2, 5/17, -2/3,...). Most repeating patterned numbers fall into this category.
\n" ); document.write( "I is the set of irrational numbers and every other number not in W, Z, or Q falls into this category.
\n" ); document.write( "Examples are
\n" ); document.write( "\"pi\" which approximates to 3.1415926
\n" ); document.write( " \"e\" which is approximately 2.71828
\n" ); document.write( " \"sqrt%282%29\" which approximates to 1.4142135.
\n" ); document.write( "Your number falls into Q.
\n" ); document.write( "It is the ratio of two integers.
\n" ); document.write( "In fact the two integers are 689 and 5247, 689/5247=0.13131313...
\n" ); document.write( "
\n" );
