They have to be even numbers.
\n" ); document.write( "If they were both odd, the product would be odd.
\n" ); document.write( "If one were odd and one even, the sum would be odd.
\n" ); document.write( "--------------------------------
\n" ); document.write( "They have to be multiples of 10.
\n" ); document.write( "The 2 LS digits are 00. If they're not multiples of 10, then one of the numbers is 25, but it's already been determined that both number are even.
\n" ); document.write( "That makes the problem:
\n" ); document.write( "what two numbers added together that equals 7 but when multiplied it equals 6?
\n" ); document.write( "That factors of 6 are 1 & 6, or 2 & 3
\n" ); document.write( "1 + 6 = 7
\n" ); document.write( "--> 10 & 60\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
