7×11×13=1001.

That's why you can take ABC, do the trick and get ABCABC, then doing again with a small enough number will result in ABCXYZABC where XYZ as a 3 digit number is ABC × 2

7x11x13=1001
So if you multiply by it you get 1000 times the number (which is the same nember with three zeros) plus the number itself (which replaces the zeros)
That's clever

I remember getting asked this at a maths challenge in primary school. Except we decided it would be easier to multiply the 3 primes together first, ruining the entire trick

[isjosh]

7*11*13 = 1001
1001*a = 1000a + a
Chosing any random three digit integer for a would result in having that theee digit number: abc times 1000 = abc000 and adding that number again ; abc000 + abc = abcabc

This works for 1001^n * a where a is a three digit number and a is less than 1001/n where n is an integer between 1 and 693.

7•11•13 = 1001
So when you multiply your 3 digit number the 1 makes up XYZ, 345 and the 1000 boosts that original number up to 345, XYZ. Put together (1000+1)345 you get 345, 345

Try multiplying with 73 and 137. It should work with 4 digit numbers. 🤯

Hey so i found something that’s pretty cool. I figured this out when i was around 10 or 11, im 13 now and have been waiting to tell someone.
So, grab any four digit number. Take the absolute value of the difference between the first and second digits, then take that as the first digit of the new number. Then repeat this for the 2nd and 3rd digit, 3rd and 4th digit, but then you do the difference between the last and 1st digit. The new number should be an entire different number, but repeat this process now again for the new number. Repeat this enough times for literally any number and it will always eventually come out to 0000. I honestly have no idea how this works but it does, and its pretty fun to mess around with on some notebook paper.

Underrated content fr some of the most interesting things I see.

If the number is small enough:

If u do it twice, the number in the middle is double the original. If u do it 3 times, the 2 numbers In The middle are triple the original number.

115 - 115, 115 - 115, 230, 115 - 115, 345, 345, 115

[Just-A-Chill-Gamer]

And the middle was 690, which is not only nice tenfold, but also 345×2!

[giovanji]

Also if you do it with a very small number with 3 digits (like 100) by doing this again and again you get a sequence that in my language is called tartaglia's triangle
100.100 (1 1)
100.200.100 (1 2 1)
100.300.300.100 (1 3 3 1)
100.400.600.400.100 (1 4 6 4 1)
This is a very cool trick!

[reznovvazileski]

First one works because 7*11*13 = 1001. By how the decimal system works, it pretty much concetenates the number to itself times 1, which is the number itself at an interval of 3 since every 3rd spacing past the first 1 is also a one.
The second one is more interesting. This happens because the middle three numbers will always be number*2 since 1001^2 = = 1002001. 499 is fine here and evades any problems, but once you go 500 it will make 1000 and carry over a 1 into your first three digits.

[jeremystone]

It works because you're telling everybody the answer is random. When you multiply two numbers your answer is never random

[EdenTheArbiter]

You are opening my mind. Please never stop! I love learning and this is amazing

[colinjava]

Remember this from school, you pick a 3 digit number, say 852 then type it in again, to get 852852.
Then divide by 7, 11, 13 and you get 852 again.
Not rocket science though.

Finally, a short that impressed me and was worth watching. Kudos to you!!!

[joiedevivre]

When performing arithmetic ALWAYS wear a lab coat.

[tamirerez]

Here is another amazing trick:
Take a 3 digits number, any number, and multiple it by 1001. Look at the result...
Isn't it AMAZING??😂

[colinpalmer]

The first 3 primes are 1 2 3. The next three are 5 7 11.

[evanhostetter]

Did you know that Pascal’s triangle numbers are powers of eleven? Cuz 1=11^0, 11=11^1, 121=11^2 and so on and on and on forever and ever
