Place value
We found a locked computer terminal. The passcode screen shows a huge number, but the security chip only reads the digit in the thousands place.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Multi-step word problems
We checked the inventory logs. To find out how many spare screws are missing, we must combine the heavy boxes and subtract the empty ones.
Solve each problem to learn its letter, then write the letters in the boxes to fill in the missing word.
Addition
A broken power dock was bypassed. We need to add up the charges of all the connected battery packs to see the total output.
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 villain drained energy from the main generator. Let us subtract the leftover power from the starting amount to find the usage.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Division facts (1-12) — the last clue
A box of backup microchips was knocked over. We must share the chips equally among the empty robot chassis to see how many each gets.
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!
