7 small cats x 7 big cats x 7 backpacks x 7 girls?
(2)(7girls) x (4)(343big cats) x (4)(2401small cats) = lol i got some insane number.
dunno what im doing wrong I got 184473632
there are 7 girls each of them has 7 backpacks and in each of those backpacks there are 7 cats. so doesn't that make it 343 big cats each with 4 legs?
Then if there are 7 small cats for every big cat that means there are 2401 small cats each with 4 legs.
add that to the 14 legs the 7 girls have, i got 18447362.

You wouldn't multiple each of the separate legs together, you add them.

i think people fall for a simple thing : they count 4 legs for the girls since cats have four and your counting more with cats.
anyway i got it wrong first 2 times quite tricky

7[GIRLS]*2[NUMBER OF LEGS EACH]=14[LEGS]
7[GIRLS]*7[BACKPACKS EACH]*7[BIG CATS EACH]=343[TOTAL BIG CATS]*4[NUMBER OF LEGS EACH]=1372[LEGS]
343[BIG CATS]*7[SMALL CATS EACH]=2401[TOTAL SMALL CATS]*4[NUMBER OF LEGS EACH]=9604[LEGS]
9604[SMALL CAT LEGS]+1372[BIG CAT LEGS]+14[GIRL LEGS]=10990[TOTAL NUMBER OF LEGS]
Simple.

10990...if you didn't get that your retarded im sorry but that was too easy
7girls= 14 legs
7^3= 343 big cats X4 = 1372 legs
7^4= 2401 small cats X4 = 9604
9604+1372+14=10990

That's exactly what I said -_-
The part where most people trip up is that they think that each girl has 7 big cats, but each girl actually has 49 big cats. The backpacks is like a "twist" or something.
It's harder than I thought it would be though, the first time I got it wrong. But I was just assuming it was a stupid problem.
