This impies they are integers. \n" ); document.write( "Let the first number be a. Then the second number is b=a+1. \n" ); document.write( "The sum of two numbers = the differnce of those two numbers \n" ); document.write( "Hence, \n" ); document.write( "a+b = b-a (b is greater than a) \n" ); document.write( "subtracting b from both sides, \n" ); document.write( "a = -a \n" ); document.write( "adding a to both sides, \n" ); document.write( "2a = 0 \n" ); document.write( "a = 0 \n" ); document.write( "===== \n" ); document.write( "b = 1 \n" ); document.write( "===== \n" ); document.write( "Check \n" ); document.write( "a+b = 0 + 1 = 1 \n" ); document.write( "b-a = 1 - 0 = 1 \n" ); document.write( "OK \n" ); document.write( " |
