MY IQ IS sooo low.

I just realized that the solution DOES NOT match your problem!

However, they use different numbers but ask the same question, so you should get the correct answer using Omi's or AoPs's method.

Sorry, but you can't post AoPS problems on the forum. It breaks their code of conduct.
