Cool math fact

111,111,111 x 111,111,111 = 12,345,678,987,654,321.

That's an pretty easy fact and even though I know how it works it's still intriguing.
Do any of you know the 1089 Process?
yes

Interestingly, he said it in post # 11

A coincidental hint! Or was it saved for ... just the right moment?

Another hint. Juxtaposition is a sort of addition.

No one knows how long the coast of England actually is.

Just something I learned when reading about fractals. It's called the Coastline Paradox if you want to check it out.

sqrt(cos(x))cos(300x)+sqrt(abs(x))-0.7)(4-x*x)^0.01, sqrt(6-x^2), -sqrt(6-x^2) from -4.5 to 4.5

I'm gonna steal that (although I know that the meme already exists).

talk about stealing hold my sqrt(cos(x))cos(300x)+sqrt(abs(x))-0.7)(4-x*x)^0.01, sqrt(6-x^2), -sqrt(6-x^2) from -4.5 to 4.5, HOW ABOUT LETS TALK SOME PRACTICE

Pick any natural number, e.g. 13
Multiply by 3 and add 1: 133 + 1 = 40
If it is even, divide by 2 and repeat until it is odd. 40 / 2 = 20, 20 / 2 = 10, 10 / 2 = 5
Repeat the process 53 + 1 = 16
16 / 2 = 8, 8 / 2 = 4, 4 / 2 = 2, 2 / 2 = 1
The sequence always ends at 1.

Some cool facts about Math and statistics:

1. In the US over 90% of married people were married on their wedding day
2. In India life leads to death 100% of the time. Together we can stop this.
3. Statistically, 50% of the Africans are half of all Africans
4. 100% of the dogs are actually not cats
5. Over 99% of the world population was born
6. The fastest truck in the world is actually faster than the rest of trucks.
7. In Asia, dead people are less likely to be killed

Ah yes, the Collatz Conjecture. Veritasium made a very interesting video about it btw:
