About Touch Natural Numbers

Small laboratory of Natural Numbers:
The Prime numbers are the building blocks of the numbers.
With this app you can:
Analyze the factors of a Composite number.
( Prime factorization of all the composite numbers between 1 and 28181: Factoring natural numbers: Prime factors).
Build a Composite number from its factors. (multiplication and division of Natural Numbers)
Localize or select a number in the Ulam Spiral.
(Only the Prime Numbers have a color in this spiral).
Verify all the possible products between Primes in a composite number with the Parabolic Sieve (Yuri Matiyasevich & Boris Stechkin).
Analyze or build a number with the Place Value activity (Addition and Subtraction of Natural Numbers)
Understand the Modulo of a number.
Know about the polygonal numbers and the numbers as the sum of two prime numbers, and as the sum of three Prime Numbers.

What is all this about? Read the nummolt blog post:

And:
The fundamental theorem of arithmetic, also called the unique factorization theorem or the unique-prime-factorization theorem, states that every integer greater than 1 either is prime itself or is the product of prime numbers, and that this product is unique, up to the order of the factors
