Example: Finding the Greatest Common Divisor
... To find the greatest common divisor of two or more numbers; 1. Write the prime factorization of each number. 2. Select each prime factor with the smallest exponent that is common to each of the prime factorizations. 3. Form the product of the numbers from step 2. The greatest common divisor is the p ...

Solutions
... This is clearly going to need algebra. It is worth thinking about whether it is best to use letters to denote the ages now or a year ago. If you do it now, then you are going to have to subtract 1 from all the letters for the first equation and add 1 to each of the letters for the second equation. S ...

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.
