You can put this solution on YOUR website!
Natural numbers are \"counting numbers\". They are positive whole numbers that you would use to count objects.
\n" ); document.write( ".
\n" ); document.write( "Which of those fall under that definition? If you were counting apples, what could you use to count them?
\n" ); document.write( ".
\n" ); document.write( "7 is obvious.
\n" ); document.write( "The negatives are obviously not.
\n" ); document.write( "What about 0? Can you \"count\" zero? The true answer is \"no\", although I have seen texts that dispute that. It's not a natural number. You don't start counting with zero, you start with \"one\".
\n" ); document.write( " $\"1%2F3\"$ is not a whole number, so no. No for 7.8 for the same reason.
\n" ); document.write( "What about the square root of 25? Tricky :-). It's 5, so it IS a natural number. Whether you write it as sq rt 25 or 5, it's the same number. \n" ); document.write( "

\n" );
