The SAS documentation provides a mathematical description of Analysis of Variance.

The Getting Started Example for PROC GLM provides a step-by-step table-by-table analysi of the numbers that are produced by PROC GLM for an ANOVA. There are also sections that describe the CONTRAST, ESTIMATE, and LSMEANS statements, along with examples.
