Let x and y be the two numbers. There are two cases: (1) we subtract y from x to get the difference (y is the minuend and x is the subtrahend), and (2) we subtract x from y to get the difference (x is the minuend and y is the subtrahend).\r
\n" ); document.write( "\n" ); document.write( "In the first case:
\n" ); document.write( "n = (x+y) - (x-y)
\n" ); document.write( "n = x + y - x + y
\n" ); document.write( "n = 2y\r
\n" ); document.write( "\n" ); document.write( "In the second case:
\n" ); document.write( "n = (x+y) - (y-x)
\n" ); document.write( "n = x + y - y + x
\n" ); document.write( "n = 2x\r
\n" ); document.write( "\n" ); document.write( "So we can say that the answer is twice the the number we choose for the subtrahend when we find the difference of the two numbers.
