Integers: An Overview

Integers are an essential part of mathematics, and are a vital concept for any person to gain a deep understanding of maths. An integer is a whole number – either a positive number such as 1,2,3… or a negative number such as -1,-2,-3…. 0 is also considered an integer. Integers are a type of number used in coding and computer programming, as well as algebra and everyday calculations.

Understanding the Basics of Integers

Integers are numbers that can be used for a range of purposes, but their main function is to count or measure objects. By counting how many apples you have in a jar, for example, you are using integers. Integers also represent other concepts, such as temperatures. The temperature of your room is likely in the form of a degree, which is an integer.

Integer Operators: Adding, Subtracting, Multiplying and Dividing

Integers enable you to make basic mathematical calculations, including addition, subtraction, multiplication and division. All these operations involve an operator and two integers, producing a result which is also an integer. For example, addtion of two integers: 3 + 5 = 8.

It’s also possible to combine operators when working with integers. As a basic example, consider the following: 6 + 4 – 2 = 8. This calculation follows the rules of order of operations and follows the path of addition (6 + 4) then subtraction (2) to arrive at the result, which is 8.

Using Integers in Algebra

Integers can also appear in equations in an algebraic setting. For example, solving x2+2x-8 = 0. In this equation, x = 2 and x = -4, the solutions to the equation which are the two integers.

Integers are an integral part of mathematics, and a basic understanding of integers can help simplify many complicated math problems. Every day, integers are used in coding, programming, and of course, calculations. Understanding the basics of integers, including operators such as addition, subtraction, multiplication and division, is essential for a solid base in math.
