What is wrong in Ma & Pa Kettle Math?

This fun video can easily convince you that 25 / 5 = 14.



Still doubting? Good!
We are being cheated right under our eyes. Ma & Pa use correct multiplication and division rules but freely mix and match digits in singles and tens places.

The last trick is the easiest to catch.

He adds all five 4th obtaining 20 correctly.
Then adds all five 1th, but places this 5 into the singles digit instead of the tens one.

This is what he should have got:
20
5
---
70

Mom does the same multiplying (I use 0s to kep digits in place):
14
05
--
20

25

when 5 should go into tens producing 70.

And in the very first argument Pa again puts 1 and 4 next to each other producing 14 instead of adding them to get 5.

Watch it a few time stopping after each math machination and you will see that 25 / 5 is still 5 and Ma and Pa are amazing actors.
