If 0 is considered a Natural number then 54 is also a valid value for x+y

[michaelempeigne]

( x + 1 ) ( y + 1 ) = 55 = 1 * 55 or 5 * 11

Therefore x+y + 1 + 1 = 56 ==> x+y = 54
or x+y + 1 + 1 = 16 ==> x+y = 14

but if x, y E N then only x+y = 14 be acceptable.

Too easy but very nice! I saw this @MathWindow
