This isn't a fact but a trick. You pick a number, anywhere between 1 and a thousand (or more), and then add each digit. For example, if you pick 348, you add 3 + 4 + 8 to get 15. Now, you underline any one digit—let’s say 4—then copy the remaining digits, so 38. Subtract the sum from this new number: 38 – 15 = 23.
Here’s the weird part: you tell only 23 to the trickster, and they instantly guess which number you underlined. I even tested this with a 9-digit number (100 million+), and they still got it right!
How does this work?

Intuitively, it's easy to understand there's infinite primes, but how do you prove it? How can we mathematically show that they don't stop appearing for some weird reason?
@UYTx
ur gonna pass me in subs soon
@Arycke
2 is the smallest prime, not 1 (by definition). Good video otherwise.
@LamGiang-i6e
This is cooler you can find a chain of numbers aren’t prime number that continues to infinite
@TheGoat62607
The Egyptian one and algorithm one was really cool! 😎 thx, appreciate ur facts. Also when is ur birthday?! (Everyone)
@phiargu
Prime numbers, but you wrote odd numbers. Correction to a correction: you started the prime numbers from 1, not 2.

Damn, even the Egyptians knew the absolute cinema 😂

Egyptian 1: yo how much time does it take to sail down the Nile? Egytian 2: “🚹”
@bro91wn
FYI 1 is not prime, the first prime is 2.

How teachers think we will use these math facts

Ancient Egyptians…. So stupid🙄🙄…
@Targetplus_GOAT
No way I am this early(3 mins) to ur vid bro.
@AdamR-b7y
Damn, an infinite number of prime numbers? How far have we gone so far (the approximate highest discovered prime)?
