My friends and I always wondered if you were to add 2 different SPF amounts to your skin, such as a 30 and 50, are you applying the sum of the two, in which this case it would be an 80 SPF?

The application is not accumulative. You would have 50 SPF.

They don't add together. They'd actually get mixed together and you'd end up with about a 40 SPF coverage because of the SPF 50 being diluted by the SPF 30.

Well, no. It would simply provide 50 SPF coverage.
Logically, if one were to apply 10 layers of the same 30 SPF sunblock, would it add up to 300 SPF?

NO! Actually anything over a 30 SPF isn't going to be doing much more but irritating your skin. It's just a marketing ploy to get you to buy there product. What the the higher number means is that there are more chemicals in the product to irritate you skin. There are 2 types of sun screens. Sun block and sun screen. If you have sensitized skin you would want to wear a sun block.

No, you would not have 80 spf. You wouldn't even have 50 at that point. If you are putting them on within a few minutes of each other, one would dilute the other, averaging out the effects. You would end up with approximately 42.5 spf.

I dont think so.... It's not like a paint that you could apply the first layer then apply the second layer.....
The best thing to do is:
Wear long sleeves, bring umbrella, try not to be under the sun... and use whitening lotion with SPF 10

I've read that you will absorb in your skin, up to the highest spf that you applied, that would be 50

You would have the protection of the 50. But I have read that the protection of 50 is not that much more than 30 b/c once you get to ~30, then there is not much more protection.
