### YouTube... Ma and Pa Kettle Math

Ma and Pa Kettle are convinced that `25 divided-by 5` equals `14`.

Pa's math...

```   5)25(1
- 5      five goes into five 1 time
===
20      five goes into 20 four times

5)25(14
- 5
===
20      five goes into 20 four times
-20
===
0

according to Pa Kettle, 25 / 5 equals 14
```

"I'll prove you using multiplication" that five times five is twenty-five...

```	  5
x 5
===
25
```

Ma takes a turn doing math to show that fourteen times five is twenty-five...

```     14
x  5
====
20      five times four is 20
+  5      five times one is 5
====
25

according to Ma Kettle, 14 x 5 equals 20
```

"I'll prove to you by addition" that fourteen times five is not twenty-five...

```     14
14
14
14
+ 14
====

begin by adding up the ones place...
4 + 4 is 8, 8 + 4 is 12, 12 + 4 is 16, 12 + 8 is 20...

Pa takes over and continues adding up the tens place...
20 + 1 = 21, 21 + 1 = 22, 21 + 1 = 23, 23 + 1 = 24, 24 + 1 = 25
```

The following was a comment about the Ma and Pa Kettle video: "Abbott and Costello do a similar 'old math' routine based on the equation of 7 goes into 28, 13 times."
