Addition
We found the switchboard at Station One. The saboteur added extra dummy circuits to overload the power. Add up the active circuits on the grid to reveal our first hidden file.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Subtraction
The cart's fuel cell is leaking rapidly! We need to calculate how much fuel was lost between the two checkpoints. Subtract the current level from the starting amount to unlock the next data node.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Multiplication facts (1-12)
The backup generator is locked behind rows of cargo containers. The layout is a massive grid of stacked boxes. Multiply the number of rows by the boxes in each row to bypass the lock and get the hair 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.
Place value
A strange signal is blinking on the speed monitor. The numbers are scrambled, and we need to identify the exact digit in the thousands place to decode the frequency. Read the digit carefully to find the tell.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Fractions of a number — the last clue
The final track switch is jammed. We have a set of light bulbs, but only a fraction of them need to be turned on to reset the mechanism. Calculate the exact fraction of bulbs to light up, and we will reveal the villain's true weakness!
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!
