Here is a 5th grade math problem. If you can open the spreadsheet, you’ll see it’s a very small list of people who have gotten the correct number. This is not a trick question. This is a real math problem, so don’t say that a bus has no legs.

There are 7 girls in a bus =14. Each girl has 7 backpacks. In each backpack, there are 7 big cats For every big cat there are 7 little cats.

Question: How many legs are there in the bus?

(The number of legs is the password to unlock the Excel sheet. If you open it, add your name, save and send it on to see who else can unlock it.)
