I have memorised the first 500 digits of p.i using a memory palace a few month ago.

Recently I was just having fun with PI and noticed a couple of things using simple maths.

It starts with 3. and then 1 and 4 and 1 and 5

3 . 1 4 1 5

So here is the simple math I used while having some fun.

For the **first 4 digits** I’ve used the digits as **"+"**

3 plus 1 is 4, 4 plus 1 is 5. = 31415

3+1 = 4

314

4 + 1 = 5

31415

Now I’ve added **all the digits before the 5 to place it after the 5**.

3+1+4+1 = 9

last digit was 5, so I placed 9 next to it.

Gives me - 314159

Next I’ve added all the **1s together** 1+1 = 2

3141592

Next I timed last digit (2) with the **first** digit (3)

2x3 = 6

31415926

Next I used the last digit minus the **second** digit

6-1 = 5

314159265

Next, I used the last digit (5), timed with with the **third** digit (4) and added the next two digits.

5x4 = 20 +15 = 35

31415926535

Next I’ve added the **last two** digits **together**

3+5 = 8

314159265358

Last digit (8) added to the **Fourth** digit (1)

8+1 = 9

3141592653589

Next is the last digit (9) + **Fifth** digit (5) - Next digit (9) + Next digit (2)

9+5 = 14

14-9 = 5

5 + 2 = 7

31415926535897

The **Sixth** digit is 9, so I simply place it next to the last digit.

314159265358979

Next is the last digit (9) divided by the **Seventh** digit (2) timed by the next and added to the next digit.

9/2 = 4.5

4.5 * 6 = 27

27 + 5 = 32

31415926535897932

So far it’s 17 digits of pi.

This has taken away some boredom .

I’m need a strong a cup of coffee now

In the UK, there is a program called “Countdown”

It’s where the participants get a bunch of numbers, and do some maths to find the target three digit number. So I started doing this with P.I to have some fun.

If you are bored and want to pass some time, why not add the next ones?

I’m not good at maths, but I like to see some crazy math tricks.

Here are the first 100 digits of p.i if you like to carry on with it.

3 . 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 2 3 8 4 6 2 6 4 3 3 8 3 2 7 9 5 0 2 8 8 4 1 9 7 1 6 9 3 9 9 3 7 5 1 0 5 8 2 0 9 7 4 9 4 4 5 9 2 3 0 7 8 1 6 4 0 6 2 8 6 2 0 8 9 9 8 6 2 8 0 3 4 8 2 5 3 4 2 1 1 7 0 6 7 9.
