In this talk, I will present two state-of-the-art theory calculations for single-inclusive processes at the LHC. I will start with the first next-to-next-to-leading-order (NNLO) calculation for light hadron production at the LHC, which finally enables global fits of fragmentation models at NNLO precision. I will then discuss how similar computational techniques can be applied to inclusive jet production and present the first calculation of single-inclusive jet cross sections at the LHC at NNLO including resummation of logarithms of the jet radius R at next-to-next-to-leading-logarithmic accuracy. Finally, I will demonstrate how the uncertainties on these results due to missing higher-order corrections can be estimated using the method of theory nuisance parameters. In contrast to uncertainties obtained using standard scale variation techniques, such uncertainties have a proper statistical interpretation, can be properly correlated and are more reliable.
