how do you conclude that 7+7=5,it's turning out to be clueless,but you say B+D=E may be true for if you assume the order of these alphabets in increasing order or assinging the number 1,3,4 to each of them respectively.....again you say 1+1=2...this also evokes question for its utility in the representation of the alphabets ....what does it denote....???

7 + 7 = 14, 1 + 4 = 5

In short, $$7+7 \equiv 5 (mod 9)$$

In fact if you try

0, 1, 2, 3, 4, 5....k

k, (k-1)...., 3, 2, 1, 0

a+b=c implies (k-a)+(k-b)=k+(k-a-b)
