There are two categories of UV light -- UVA and UVB -- that we consider in terms of sunscreen. UVB causes sunburn, and UVA has more long-term damaging effects on the skin, like premature aging. SPF, or sun protection factor, numbers were introduced in 1962 to measure a sunscreen's effect against UVB rays.

What is the highest number of SPF in sunscreen?
I have a bottle of spray on sun screen, it had an SPF rating of 110. I have very white skin ;) Previous answer: As far as I've seen 100. It must also be kept in mind that after a particular number the SPF does not count. What counts is whether the sunscreen gets washed out due to sweat or water and whether it gets wiped out due to clothing. If so then even if you have a SPF 200 sunscreen, you will need to reapply as required.
Would adding spf 30 sunscreen to spf 50 sunscreen make it spf 80 sunscreen?
No. SPF 30 lets in 1/30 of burning UV rays, while SPF 50 lets in 1/50. Adding the two together is pointless and would not result in high levels of skin protection.

Does the SPF count?
"The Sun Protection Factor (SPF) displayed on the sunscreen label ranges from 2 to as high as 50 and refers to the product's ability to screen or block out the sun's harmful rays. For example, if you use a sunscreen with an SPF 15, you can be in the sun 15 times longer that you can without sunscreen before burning. Consumers need to be aware that SPF protection does not increase proportionally with an increased SPF number. While an SPF of 2 will absorb 50% of ultraviolet radiation, an SPF of 15 absorbs 93% and an SPF of 34 absorbs 97%." from http://www.melanomafoundation.org/prevention/facts.htm
