Clue 1

Percentages

We scanned the mainframe database and found a partially corrupted log. Solve this percentage of the code to reveal the first clue.

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

50% of 46 =T

50% of 26 =E

60% of 75 =D

20% of 120 =R

10% of 360 =G

40% of 50 =A

10% of 70 =U

5% of 760 =S

50% of 8 =H

20% of 170 =N

40% of 65 =W

25% of 36 =O

10% of 190 =B

40% of 55 =L

Clue 2

Exponents

The signal strength of the rogue robot grows exponentially. Calculate the power power-ups to track down where its signal is strongest.

Clue 5

Division facts (1-12) — the last clue

The backup batteries need to be shared equally among our tracking drones. Divide the cells so we can launch the search.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

40 ÷ 8 = ?

77 ÷ 7 = ?

120 ÷ 12 = ?

84 ÷ 7 = ?

81 ÷ 9 = ?

28 ÷ 4 = ?

30 ÷ 10 = ?

24 ÷ 6 = ?

66 ÷ 11 = ?

5 ÷ 5 = ?

72 ÷ 9 = ?

Step 2 — cross out the sentence with each answer

1.The villain tunnels deep under the floor, then charges its battery backup.

2.The villain lifts heavy steel girders, then grapples a container of chips.

3.The villain lifts heavy steel girders, then scans the room with radar.

4.The villain tunnels deep under the floor, then seals the exit hatch shut.

5.The villain tunnels deep under the floor, then scans the room with radar.

6.The villain slices through security barriers, then seals the exit hatch shut.

7.The villain melts the titanium vault door, then seals the exit hatch shut.

8.The villain melts the titanium vault door, then blasts a loud warning signal.

9.The villain zooms across the ceiling, then grapples a container of chips.

10.The villain zooms across the ceiling, then scans the room with radar.

11.The villain slices through security barriers, then scans the room with radar.

12.The villain zooms across the ceiling, then blasts a loud warning signal.
