PLEASE BE NEAT AND ORGANIZED.

Level 1: Take Flight: This puzzle is one that Mrs. Bailey found in a airplane flight magazine. She thought you might enjoy it. Directions: In the subtraction problem below, each letter stands for one digit from 0-9. Each letter is a different number. Find the value of A, B, and C.

A B A A=? B=? C=?

- C A

- C A

**A B**

Level 2: Code Breakers: This puzzle is adapted from puzzles found in a book titled Code Breakers published by Mindware. Solve the puzzle by determining what number belongs in place of each letter. All the numbers are whole numbers, positive numbers, and they can’t be zero. The numbers can be one digit (ex. 8) or more than one digit (ex. 13). In the puzzle, the letter A must always be the same number throughout the puzzle, and the same goes for B and C.

A=? B=? C=?

B + C = 13

C + C = 12

A + B = 10

Level 3: Advanced Code Breaker: Read the instructions above for Level 2, except instead of A, B, and C you will be have D, E, and F. Now try to solve this puzzle.

D=? E=? F=?

D + E + F = 14

F + E + E + F = 22

D + E + F + D + E = 21
