Three Squirrels Were Sitting On Animal Hides
Three squirrels were sitting on animal hides…
The first squirrel was sitting on a rabbit hide and weighed one pound.
The second squirrel was sitting on a wolf hide and weighed two pounds.
the third squirrel was sitting on a hippopotamus hide and weighed three pounds.
This proves that the squirrel on the hippopotamus is equal to the sum of the squirrels on the other two hides.
