A little girl was failing math. Her mother enrolled her in Catholic school in the hopes to improve her math grades. During the first marking period, her mother noticed a dramatic improvement in her math studies. The girl would refuse playing with friends and eating dessert after dinner in order to study more.
On report card day, her mother was astonished to see that her daughter got an A+ in math. She asked her daughter, “Why the sudden change of attitude about math -- do the nuns punish you?” The girl replied, “No, but when I saw the little man on the wall nailed to the plus sign, I knew that this school is very serious about math!”
