Math Brain Teaser

[darctangent]

I came up with this after seeing a similar one on Facebook:

1+4=23
2+5=33
3+6=25
7+8=?

Let me know what you think.

I think I have spent far too much time on this without getting anywhere...now I feel dumb.

[darctangent]

At least you're giving it a try.

[Brian706]

Hmmm, i can't find the pattern or correlation. I'll come back to it later and see if anything clicks.

[AndrewParr]

I saw your brilliant reply to the question on Facebook, so I will keep quiet.

[darctangent]

I'm glad some people are working on it.

[Lilmike14]

Let me know what you think.

I think you're evil

[Brian706]

Still, nothing is clicking. Every time I think I find a pattern, with the first two, the third one throws a wrench in my plan.

Is this something anyone could potentially figure out through logic/reasoning; or does this require some sort of advanced math wizardry that not many people would get?

[darctangent]

Not too advanced, I would say. There are four separate equations that follow the same rules but are independent, just like they would be for any regular equations.

Ive been banging my head on this again and again. Everytime I find something thats works on 2of them...aaahhhh!
