A graphic that accompanied an article Saturday about a new progress reporting system to be tested in Baltimore County schools misstated a mathematical term. The correct algebra term is commutative property.

An article yesterday about Baltimore's mayoral race misstated the congressional district of U.S. Rep. Elijah E. Cummings. He represents Maryland's 7th District.

An obituary in yesterday's editions misstated the time of memorial services for Stefan E. Martin. Services are scheduled for 3 p.m. Saturday at Evans Funeral Chapel at Harford Road and Putty Hill Avenue in Parkville.

The Sun regrets the errors.
