Definition
-
An even number is a mathematical term used to describe a whole number that is divisible by 2 without leaving any remainder. In other words, an even number can be divided evenly into two equal parts or groups. When an even number is divided by 2, it results in an integer value. The basic rule to determine whether a number is even or not is by examining its last digit. If the last digit of a number is 0, 2, 4, 6, or 8, then it is classified as an even number.
Even numbers are commonly represented by the form 2n, where "n" represents any positive or negative integer. They form an essential part of arithmetic and number theory. Furthermore, they play a significant role in various mathematical concepts, such as algebra, geometry, and calculus.
In the context of practical applications, even numbers are frequently encountered in daily life situations, including counting objects, measuring quantities, and dividing resources equally. Even numbers are useful in mathematical operations, such as addition, subtraction, multiplication, and division, as well as in solving equations and determining patterns.
Overall, an even number refers to any whole number that can be divided by 2 without leaving a remainder, enabling equal division and mathematical manipulation.
Etymology of EVEN NUMBER
The word "even" has an Old English origin, derived from the Old English word "efen", which means "equal" or "level". This term evolved from the Proto-Germanic word "ebnaz", meaning "equal" or "even". The concept of "evenness" has been associated with numbers since ancient times. The word "number" comes from the Latin word "numerus", which means "a number, quantity, or sum". Thus, the term "even number" essentially combines the Old English term "efen" with the Latin term "number" to describe a quantity that is divisible by 2 without leaving a remainder.
