\"Divisibility\" is the ability to divide one number by another number with no remainder. Here are some examples: (Note: the slash (/) means \"divided by\")\r
\n" ); document.write( "\n" ); document.write( "9 is divisble by 3 because \"9%2F3+=+3\" with no remainder.\r
\n" ); document.write( "\n" ); document.write( "51 is divisble by 17 because \"51%2F17+=+3\" with no remainder.\r
\n" ); document.write( "\n" ); document.write( "But:\r
\n" ); document.write( "\n" ); document.write( "13 is not divisble by 4 because \"13%2F4\" = 3 and remainder of 1.\r
\n" ); document.write( "\n" ); document.write( "It would be very useful for you to become familiar the \"Divisibility rules\"\r
\n" ); document.write( "\n" ); document.write( "A number is divisble by...\r
\n" ); document.write( "\n" ); document.write( "2 if it is an even number.
\n" ); document.write( "3 if the sum of the digits is divisible by 3.
\n" ); document.write( "4 if the last two digits (tens and ones digits) are divible by 4.
\n" ); document.write( "5 if the one's digit is 5 or 0.
\n" ); document.write( "6 if the number is divisble by both 2 and 3.
\n" ); document.write( "7 No rule for 7.
\n" ); document.write( "8 No rule for 8 but try 2 then 4.
\n" ); document.write( "9 if the sum of the digits is divisble by 9.
\n" ); document.write( "10 if the ones digit is 0.
\n" ); document.write( "
\n" ); document.write( "
\n" );
