I said 'x' equals 12, you bastard!

PALM SPRINGS, Calif. - A teacher and a 14-year-old student were arrested after trading blows during an argument over taking out trash at the desert's Riverside County Community School.

Teacher Thomas Silva, 61, was arrested and booked for investigation of willful cruelty to a child, while the teenager was arrested for battery on a school employee, Sgt. Mitch Spike said Thursday. Both were released.

At about 11:20 a.m. on Wednesday, Silva asked the student to throw out the trash and the teen refused, Spike said. They argued and the student shoved Silva, who then slapped the student, the sergeant said.

The student then slapped the teacher and the teacher punched the student at least three times in the head, Spike said.
