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 £10 book token will be awarded to the sender of the first correct answer opened on Thursday 16 November. The Editor’s decision is final. Please send entries to Enigma 844, 51¶¯Âþ, King’s Reach Tower, Stamford Street, London SE99 0BB. The winner of Enigma 838 was C. J. N. Eacott of Winchester, Hampshire.
