... remainder 1 when divided by 9. This can be reformulated as follows. Adding the digits of any even perfect number (except 6), then adding the digits of the resulting number, and repeating this process until a single digit is obtained — the resulting number is called the digital root — produces the nu ...

... Closed intervals consist of all the numbers that fall between two numbers, including the numbers themselves. That the endpoints are included is indicated by square brackets. Example 2: [ -4, 4 ] is a closed interval. It consists of all the numbers that fall between –4 and 4, including the endpoints ...

Finding Carmichael numbers
... Recall that Fermat’s “little theorem” says that if p is prime and a is not a multiple of p, then ap−1 ≡ 1 mod p. This theorem gives a possible way to detect primes, or more exactly, non-primes: if for some positive a ≤ n − 1, an−1 is not congruent to 1 mod n, then, by the theorem, n is not prime. A ...

Let’s experiment a bit with Mathematica. We denote the exact number of primes below n by (n). The Prime Number Theorem (PNT). The number of ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
