MATH PUZZLE: Can you replace the question mark with a number?

Photoelectric cell

In 1925, the photocell device was given its first U.S. public demonstration. It was shown by the Westinghouse Electric and Mfg Co at the Electrical Show at Grand Central Palace in New York. The photocell was used to count objects by acting as a sensor as each object passed through and interrupted a beam of light. The device was also utilized as a sensor to detect when a person approached a door, which opened as a circuit was activated.«

Little Zachary was doing poorl...

Little Zachary was doing poorly in math. His parents, after exhausting all other incentives, finally decided to enroll him in the local Catholic School. After the first day, Little Zachary came home with a very serious look on his face. He went straight to his room and started studying. This continued for some time. His mother was baffled as to why he had become so dedicated.
Finally, Little Zachary brought home his report card. He quietly laid it on the table and went to his room to study. With great trepidation, his mother looked at it and, to her surprise, Little Zachary go an "A" in math. She asked, "Son, what was it? Was it the nuns, the books, the discipline, the uniforms?"
Little Zachary said, "No!"
"What was it?" she asked.
Little Zachary looked at her and said, "Well, on the first day of school, when I saw that guy nailed to the Plus Sign, I knew they weren't fooling around."
