OT: Interesting math problem...

[spoon]

Not much time, but it looks like:

V = 0
I = 5

I+I=10 but V belongs to (0,9).

Most obvoius solution is that ALL letters represent 0.

Erm... that would make V = 0, and there would be a 1 carried to the next column.

V=0 was my first attempt, but only works if you have T=D=1 and E=V=0, which may or may not fall under the guideline.

If you can have letters sharing the same number, then all letters should be 0; much easier and faster.

The thing is the book he had didn't indicate if numbers could share the same value. It would be nice if they could as everyone said 00000+00000=00000 is a simple solution.

Unless this book is reknowned for giving trick questions, this is most likely not the solution.

That is what I am thinking. As far as I know the book is just a regular math book for his grade. Unfortunately they cut the answers out of the back...

Fyron, that's why I quickly deleted my post. But not quickly enough.

I remeber that I saw such tasks in a school. Common way to solve them is to rewrite example to:

10000*T+1000*R+100*I+10*E+D+10000*D+1000*R+100*I+1 0*V+E-10000*R-1000*I-100*V-10*E-T=0

With additional condition it should be quite easy to solve.

Got it:

17465 +
57496 =
-------
74961

T=1
R=7
I=4
E=6
D=5
V=9

I brute forced it, not having time for fancy shmancy formulae. (so, I could be wrong, very wrong!)

well if e = 0

does not matter what the other letters are
