Barack Obama may have had a tough week, but he walked into a room of people happy to see him Friday morning when he visited children at Moravia Park Elementary School in Baltimore. The president toured an early childhood education program and sat down with pre-K students who were discussing their favorite zoo animals.
Obama asked how old the students were and quizzed some of the kids on basic math. After the students answered a few addition questions, one student hesitated on a subtraction problem. “Subtraction is tougher than addition,” Obama said.
