Let James' house number be \"x\", half of the number will be \"x%2F2\"
\n" ); document.write( "Now if James multiplies his house number and half his house number together and get 288, we have the equation:
\n" ); document.write( "\"x%2A%28x%2F2%29+=+288\"
\n" ); document.write( "\"%28x%5E2%29%2F2+=+288\"
\n" ); document.write( "\"x%5E2+=+144\"
\n" ); document.write( "\"sqrt%28x%5E2%29+=+sqrt%28144%29\"
\n" ); document.write( "\"x+=+12\"
\n" ); document.write( "So his house number is 12
\n" ); document.write( "TA-DAH
\n" ); document.write( ":D
