Multiplication facts (1-12)
Our scouts found rows of shipping containers knocked over by the escaping mech suit. If there are several neat rows of crates, we can multiply them to find the total damage.
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 thief drained power from our backup battery bank to jumpstart their heavy gear. Our screen shows that only a fraction of the total power cells are still fully charged.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Order of operations
To crack the locked flight log of the stolen vehicle, we must run a complex command line. Solving this multi-step equation using the proper order of operations will reveal the flight path.
Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.
Rounding
The long-range radar is glitching and cannot give an exact weight for the getaway craft. The screen only displays the estimated weight rounded to the nearest thousand tons.
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
We need to distribute the remaining energy shields equally among our shoreline defense towers. Dividing the total shield units by the number of active towers will keep Tokyo safe.
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!
