Luyện nghe bài hát Three Is A Magic Number

Three is a number,
Yes it is, it's a number.
in the ancient, mystic trinity
You get three as a number.

The and the present and the future.
Faith and and Charity,
The heart and the brain and the
you three as a magic number.

It takes three legs to a tri-pod
Or to a table stand.
It takes three wheels to make a
a tricycle.

Every triangle has corners,
Every triangle has sides,
No more, no less.
You have to guess.
When three you can see
It's a number.

A man and a had a little baby,
Yes, did.
had three in the family,
And a magic number.

3-6-9, 12-15-18, 21-24-27, 30.
3-6-9, 12-15-18, 21-24-27, 30. *
Multiply backwards from times ten:

Three time ten is (30), times nine is (27),
Three times eight is (24), three times is (21),
Three times six is (18), three times is (15),
Three times is twelve,
And times three is nine, and three times two is six,
And times one is three of course.

Now the pattern once more:
Three! . . .3-6-9
Twelve! . . .12-15-18
Twenty-one!. . .21-24-27. . .30

Now from 10 backwards:
Three time ten is (30 - going), three times nine is (27),
Three eight is (24), three times seven is (21),
Three six is (18), three times five is (15),
Three four is twelve,
And times three is nine, and three times two is six,
And times one...
is it?!
Three!
Yeah, That's a number.

A man and a had a little baby.
Yes, did.
had three in the family.
That's a number.

Now the multiples of three come up three times in set of ten. In the first ten, you get 3-6-9, and in the teens ten it's 12-15 and 18, and in the twenties you get 21-24-27 and it comes out even on 30.
