Elementary, My Dear: School House Rock video about multiplying by Two

Lyrics

Forty days and forty nights, didn't it rain, children?
Not a speck of land in sight, didn't it, didn't it rain?
But Noah built the ark so tight, they sailed on, children.
And when at last had the waters receded
And the dove brought back the olive tree leaf
He landed that ship near Mount Ararat
And one of his children grabbed Noah's robe and said,
"Hey dad, how many animals on this old ark anyway, huh?"

Elementary, my dear, 2 x 2 is 4
Elementary, my dear, 2 x 3 is 6
Elementary, my dear, 2 x 4 is 8
Elementary, my dear, 2 x 5 is 10

2 x 1 is 2, of course , and it must occur to you
You get an even number every time you multiply by 2

Elementary, my dear, 2 x 6 is 12
Elementary, my dear, 2 x 7 is 14
Elementary, my dear, 2 x 8 is 16
Elementary, my dear, 2 x 9 is 18

2 x 10 is 20
11 twice 22
Double 12 that's 24
13 twice is 26
14 twice is 28
15 twice is 30
Now you build it up on 30

16 twice is 32, elementary
17 twice is 34, elementary
18 twice is 36, elementary
19 twice is 38, elementary

20 twice is 40, and it must occur to you
You can double any number, all you do is multiply by 2

Elementary, my dear, 2 x 2 is 4
Elementary, my dear, 2 x 3 is 6
Elementary, my dear, 2 x 4 is 8
Elementary, my dear, 2 x 5 is 10

Now, if you want to multiply 2 times 174, or some big
number like that, 2 times 174 equals 2 times 100, plus
2 times 70, plus 2 times 4, that's all. So 2 times 174
equals 200, plus 140, plus 8, or, 348, it's elementary.

Elementary, elementary

Twice 32 is 64, elementary
Twice 33 is 66, elementary
Twice 34 is 68, elementary
Twice 35 is 70, elementary

Yeah, yes! It's elementary, yeah...

Now, what's 2 times 98?
Aww, that's hard!
No, it's very simple
2 times 98 equals 2 times a 100, minus 2 times 2
That's 200 minus 4: 196
Elementary!

Forty days and forty nights, didn't it rain, children?
