... In this expression prime factorization has been done. Q.10. Determine if 25110 is divisible by 45. Ans. The unit's digit of 25110 is 0. So, 25110 is divisible by 5. Also, sum of the digits = 2 + 5 + 1 + 1 + 0 = 9, which is divisible by 9. So, 25110 is divisible by 9. Now, 5 and 9 are co-prime number ...

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.
