Stump the Chump
Okay, can anyone help me solve this math puzzle? I keep thinking I've got the answer only to get shut down. And, as your math teacher always said, "show your work." I want to know where I'm going wrong. ArpatubesPuzzle

Apparently, it works like this:
7 kids x 2 legs = 14 kids' legs.
49 rucksacks x 7 big cats = 343 big cats. Multiply by 4 to get 1,372 big cat legs.
343 big cats x 7 small cats = 2401 small cats. Multiply by 4 to get 9,604 small cat legs.

343 big cats x 7 small cats = 2401 small cats. Multiply by 4 to get 9,604 small cat legs.
So 14 + 1,372 + 9604 = 10,990 legs.
I did it backwards:
start at the end, 7 small cats for each big = 7 * 4 = 28
Each big cat is associated with 28 legs.
There are 7 big cats, therefore, you have 7 * 28 = 196.
But don't forget to add on the 4 legs for each of the 7 big cats, 196 + 28 = 224.
So each sack has 224 legs.
There are 7 sacks per kid, so 7 * 224 = 1568 legs that go with each kid.
There are 7 kids so 1568 * 7 = 10976.
Then you just add two legs for each of the 7 kids and get 10976 + 14
10990 legs
