Clue 1

Fractions of a number

The suspect dropped a heavy box of golf balls while fleeing. The club caddy noticed that exactly two fifths of the balls were cracked which helped us narrow down our first major lead.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

1/2 of 6 =T

1/6 of 30 =P

3/10 of 70 =V

1/8 of 104 =D

1/4 of 96 =M

2/5 of 35 =H

1/5 of 95 =U

3/5 of 65 =E

2/4 of 8 =A

4/6 of 9 =C

1/4 of 48 =L

1/10 of 20 =J

5/8 of 56 =I

1/8 of 56 =N

2/6 of 69 =G

1/4 of 80 =O

0/16 letters found

Clue 2

Order of operations

We found a coded message hidden inside a thriller novel in the lounge. To read the secret locker combo and find the next clue we must solve a multi step equation.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

3 + 4 × 2 =T

22 + 5 × 6 =I

11 × 8 - 13 =C

7 × 7 - 2 =N

12 × 4 - 18 =W

3 × 10 - 8 =R

3 × 11 - 7 =G

7 × 3 - 11 =D

6 + 8 × 4 =A

6 × 12 - 21 =M

8 + 6 × 7 =S

2 + 2 × 2 =H

3 × 10 - 16 =E

0/13 letters found

Clue 3

Multiplication facts (1-12)

The thief ran through the storage room knocking over five rows of golf bag shelves with six bags in each row. Multiplying these groups together leads us to a clue about their weakness.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

Clue 4

Rounding

The security laser scanned the thief's escape golf cart but the damaged screen only shows the weight rounded to the nearest thousand. Rounding the display correctly reveals a new clue.
