\n" ); document.write( "\n" ); document.write( "You may add \"400%2B700%2B900=2000\", then add the \"tens\" and \"ones\" \"52%2B21%2B08=81\", and lastly add these two numbers together \"2000%2B81=2081\".\r
\n" ); document.write( "\n" ); document.write( "or, you may add \"two\" numbers at a time: \"452%2B721=1173\", hen add third one to that sum: \"1173%2B908=+2081\".
