Ronnie, liza, vivien, and vina are classmates. They send each other a Valentines card. Find the number of Valentines cards they send altogether
We've got 4 classmates. Which means each person sends 3 Valentine's cards (to everybody else in the class but themselves):
3 * 3 * 3 * 3 or 4 * 3 = 12 Valentine's cards.
