Last week: 40
This week, start counting…
There are 7 girls in a bus.
Each girl has 7 backpacks.
In each backpack, there are 7 cats.
For every cat, there are 7 kittens.
How many legs are there in the bus?
PS: Paws are considered legs, and a cat has 4 paws.
PPS: This is a real math problem, not a trick question.
The trick of the week
