### GC: Math -- An International Language

This week the Geek Challenge is from a local treasure hunt that I took part in a couple of weekends ago. Here goes...

 C O C A + C O L A O A S I S

L = 0
I = 7
L = 3
I = 8

I will give out the answer in a few days if no one has all ready answered the question.

For what it's worth.

We immediately have O=1.
From the above, S=2 or S=3. Since A+A=S (mod 10), we know S is even, hence S=2.
From the same addition above, and assuming A!=O, we determine A=6.
Since C+C=16, we get C=8.
OK, we now have 1 (carry from A+A) + 8 (C) + L = I, with no carry. This leads to L=0, I=9.

8186 + 8106 = 16292

What was the question?

John,

You got it. The question was to figure out which of the options was correct:

L = 0
I = 7
L = 3
I = 8

So you got it, L is equal to 0.
