Elementary arithmetic is a branch of mathematics involving addition, subtraction, multiplication, and division. Due to its low level of abstraction , broad range of application, and position as the foundation of all mathematics, elementary arithmetic is generally the first branch of mathematics taught in schools.
The academic year in India normally starts from June/July till March/April for students in Class 1 to Class 8. For students who are in Class 9 and 11, the year starts from June/July till February/March ending earlier than usual so the students can be promoted to Class 10 and 12 (respectively) early. The academic year for class 10 and 12 is from ...

Powers in scientific notation (example: 340,000,000 in scientific notation is 3.4 × 10 8) Identifying Probability; Solving Square roots; Pythagorean Theorem [4] Pre-algebra may include subjects from geometry, especially to further the understanding of algebra in applications to area and volume.
Arithmetic is closely related to number theory and some authors use the terms as synonyms. [8] However, in a more specific sense, number theory is restricted to the study of integers and focuses on their properties and relationships such as divisibility, factorization, and primality. [9] Traditionally, it is known as higher arithmetic. [10]
There were 17 participants from 10 countries. The World Cup involved the following contests (and two surprise tasks): Adding ten 10-digit numbers, 10 tasks in 10 minutes Winner: Alberto Coto (Spain); 10 correct results; 5:50 minutes, world record; Multiplying two 8-digit numbers, 10 tasks in 15 minutes Winner: Alberto Coto (Spain), 8 correct ...
The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones Arithmeticae, published in 1801. A familiar use of modular arithmetic is in the 12-hour clock, in which the day is divided into two 12-hour periods. If the time is 7:00 now, then 8 hours later it will be 3:00.
In mathematics, an operation is a function from a set to itself. For example, an operation on real numbers will take in real numbers and return a real number. An operation can take zero or more input values (also called "operands" or "arguments") to a well-defined output value.
