We compare the size of the sets of natural numbers, integers, rational numbers and real numbers.
Category: Proofs
We look at simple yet elegant proofs that show the creativity and beauty of mathematics.
A number bigger than infinity!
We show that there is something bigger than infinity.
What are the integer solutions of x4+y4=z4?
We show that Fermat's Last Theorem holds for the case n=4.
Fundamental Theorem of Arithmetic
We show that every natural number can be factored uniquely into the product of primes.
Those are some prime irreducibles
We show that the irreducible natural numbers are also prime.
