... The first method is to simply start writing all the multiples of both denominators, beginning with the numbers themselves. Here's an example of this method. Multiples of 4 are 4, 8, 12, 16, and so forth (because 1 × 4=4, 2 × 4=8, 3 × 4=12, 4 × 4=16, etc.). The multiples of 6 are 6, 12,…--that's the ...

... (4) Observe that for the first few positive integers n, the number n2 − n is a multiple of 2. For example, 12 − 1 = 0, 22 − 2 = 2, 32 − 3 = 6, 42 − 4 = 12, etc. Is this always true? In other words, is n2 − n always a multiple of 2? Similarly, the numbers 13 − 1 = 0, 23 − 2 = 6, 33 − 3 = 24, 43 − 4 = ...

Arithmetic
Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
