In W2004-202, Anil re-introduced the equation 11 + 2 = 12 + 1. Not only is this obviously true in this numeric form, but when written ELEVEN + TWO = TWELVE + ONE, the sum of the letter values on the left (taking A = 1 etc) equals the sum of the letter values on the right, viz 121. In this case, it is because the same letters are used on both sides.
