You can put this solution on YOUR website!
if two numbers are odd, then thier sum is even
\n" ); document.write( "-------------------
\n" ); document.write( "That shows it's true for 5 and 7, but not in general.
\n" ); document.write( "-----------
\n" ); document.write( "Odd numbers can be expressed as 2n+1, where n is any integer (odd or even).
\n" ); document.write( "Another odd number is 2m+1, same stiputation.
\n" ); document.write( "-------------------
\n" ); document.write( "The sum of any 2 odd numbers is:
\n" ); document.write( "2n + 1
\n" ); document.write( "2m + 1
\n" ); document.write( "-------
\n" ); document.write( "Sum = 2(m+n) + 2
\n" ); document.write( "Whether the sum of m and n is odd or even, 2 times it is even. Add 2, still even.
\n" ); document.write( " \n" ); document.write( "

\n" );
