IN the additions shown left, the combined sum of additions (I) and (II) equals the sum of addition (III).

In all additions, I have replaced the digits with letters and question marks. Different letters stand for different digits, but the same letter stands for the same digit whenever it appears.

A question mark can be any digit and in fact, with some of the question marks, you even have a choice of digits.

Please send in your ADDITIONS.

A 拢10 book token will be awarded to the sender of the first correct answer opened on Thursday 16 November. The Editor鈥檚 decision is final. Please send entries to Enigma 844, New 杏吧原创, King鈥檚 Reach Tower, Stamford Street, London SE99 0BB. The winner of Enigma 838 was C. J. N. Eacott of Winchester, Hampshire.
