OT: Interesting math problem...

[Ragnarok]

So my cousin has a math problem that none of us can figure out...Here on the forums I am sure someone can figure it out within like say 30 seconds so I will time you...

But here is the problem:

TRIED
+DRIVE
------
=RIVET

Each letter represents a number from 0-9. That is pretty much all the help/hint they give in my cousins book for homework as well. I believe this is 9th grade stuff.

But if someone could help me out on this and/or explain how best to go about answering this problem that would be great.

*Slaps self* Nevermind; I mixed up the Last two sums, and came to the wrong conclusion.

Heck, I barely passed algebra, even in the 9th grade. Can't help you.

[Alneyan]

The only solution I have been able to find is every letter is equal to 0. It is technically a solution; 00000+00000=00000.

Can two letters (or more) share the same value? Do you know if the final result has five figures, or could the = be a sixth number? (Sounds unlikely, but hey, who knows?)

Not much time, but it looks like:

V = 0
I = 5

well if e = 0

does not matter what the other letters are

aiken said:

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.

[Alneyan]

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.
