I remember this from a book. The puzzle is: The sum of the factors of 360 is 1170. What is the sum of the reciprocals of the factors of 360? At first glance, it might seem impossible to solve, but when you look at it deeper, it's easy. Let's do the classic: 1/1 + 1/2 … Continue reading A big number that shrinks down to about three

There is a very hard, very hard…
Hey, it's the lousy author, back with another extraordinary enigma puzzle, and I do have to say, Uncle Bungle is really messed up.
RSA Factoring Challenge
The RSA Factoring Challenge is a set of factorisation challenges that involve numbers with hundreds of digits. The highest one cracked was RSA-250, which was 250 digits long, 829 bits, and was factored in February 2020 by Fabrice Boudot, Pierrick Gaudry, Aurore Guillevic, Nadia Heninger, Emmanuel Thomé, and Paul Zimmermann (what's with the cool names?). … Continue reading RSA Factoring Challenge
One is?
One!Anybody I mean, yeah. But in a prime/composite definition? It's neither, the one exception, the golden, whatever. Why is it not prime? Let's have a look. Take 25321, a prime number. 1 is also prime, right? So the factorization of 25321 would be 25321 and 25321*1 at the same time. But we have broken two … Continue reading One is?
Okay, WHAT?!?!
So, um, this is going to be ALL ABOUT FOREIGN LANGUAGES. Vaay Bu eğlenceli olacak! (Turkish for Whoo! This will be fun!) No, this page ain't going to be in a foreign language. But you can translate it. This is about math stuff that uses other languages. Many are Greek, so watch out! Delta (Δ), … Continue reading Okay, WHAT?!?!
Transcendental numbers!
What are those?!?! Well, here's your answer!ME, THE AUTHOR Transcendental numbers are numbers that you can't do anything to it to get an integer. Besides power of 0, divide by itself, blah blah, blah. More formal: In mathematics, a transcendental number is a real number or complex number that is not an algebraic number—that is, not a root (i.e., solution) of a nonzero polynomial … Continue reading Transcendental numbers!
P=NP is a part of … Millennia!
How many Math questions are there? Obviously, there's infinitely many. But how many problems can be solved quickly? A LOT! What about having the answer verified? MILLIONS OF BILLIONS! The P=NP question ask whether a question that can be verified quickly (P) can also be solved quickly (NP). Can you solve this? Hello. The Millennium … Continue reading P=NP is a part of … Millennia!
