Hi, math detectives. I'm on the scene of our latest crime. Someone has held up the Cashflow Bank and stolen something more valuable than money.

"It all began this morning," said Mr. Bond, the bank manager. "A strange man wearing a purple hat and striped suit entered the bank. He walked up to my counter and reached into his vest pocket. I thought he was taking out his wallet, but instead he pulled out a shiny silver watch and began to swing it back and forth, back and forth. I almost fell asleep gazing at its strange reflections."

"The next thing I remember, the man tipped his hat and raced out the door. I thought it was kind of odd, but I brushed it off and went back to work on my computer. Then I noticed something very strange about the numbers in the bank accounts. I called you right away."

Mr. Bond showed me this chart on his computer screen.

Account Name	August	September	Aug-Sept Total
Dyme A. Duzen	$*0.00	$15.00	$35.00
Wood N. Nickel	$ 3.00	$1*.00	$15.00
Penn E. Lane	$10.00	$*3.00	$33.00
Monthly Total	$33.00	$50.00	$83.00

"That man stole a number from our computer system and replaced it with stars," he cried. "Oh, Math Maven! You have to help me find the missing number to make sense of all the accounts."

"Why, that no good, number-napper is none other than the Mad Adder!" I said. "Don't worry, Mr. Bond. My math detectives are on the case."
