The square root of a number is the value that, when multiplied by itself, results in the original number. It is a special exponent related to squares. Take the number 16 as an example. When 4 is multiplied by itself, the product is 16, expressed as 4 × 4 or 32. In this case, the exponent is 2, denoting a square. Now, if the exponent is 1/2, it signifies the square root of the number. For instance, √n is equivalent to n(1/2), where ‘n’ represents a positive integer. What is a Square Root? A square root of a number ‘a’…
Exponents, also known as powers or indices, are mathematical notation that represents repeated multiplication of a number by itself. They play a fundamental role in mathematics and are denoted by a superscript number. Here’s an introduction to exponents!! What are Exponents? Exponents, also known as powers or indices, are mathematical notations used to represent repeated multiplication of a number by itself. They simplify the expression of large numbers or repeated operations and play a crucial role in various mathematical concepts. The basic notation for exponents is written as an, where a is the base and n is the exponent. Here’s…
What is Linear Inequalities? Linear inequalities are mathematical expressions involving linear functions that express a relationship between two variables and indicate the relative positions of values on a number line. A linear inequality is similar to a linear equation, but instead of equating two expressions, it asserts that one expression is greater than (>), less than (<), greater than or equal to (≥), or less than or equal (≤) to another. The general form of a linear inequality in one variable x is: Here, a, b, and c are constants, and x is the variable. The inequality symbol (<, ≤, >,…
Addition and Subtraction of Algebraic Expressions: Unraveling the Basics In the world of algebra, mastering the art of adding and subtracting expressions is fundamental. Let’s dive into the basics of these operations to uncover the rules and techniques that make algebraic arithmetic a powerful tool. 1. Addition of Algebraic Expressions Like Terms in Addition When adding algebraic expressions, focus on combining like terms. Like terms have the same variable and exponent. 3x+2x=5x 7y−2y=5y Addition with Constants Combine constants just like you would with variables. 4+2=6 8a + 5a = 13a 2. Subtraction of Algebraic Expressions Subtracting Like Terms Similar to…
Spheres are one of the most elegant and perfect geometric shapes in the world of three-dimensional geometry. Their beauty lies in their simplicity and symmetry. In this comprehensive tutorial, we will explore everything you need to know about spheres, from their definition and properties to their real-world applications and mathematical significance. What Is a Sphere? A sphere is a three-dimensional geometric shape that is perfectly round and symmetrical. It is often described as the set of all points in space that are equidistant from a common center point. This common center point is called the “center” of the sphere, and…

A parallelogram is a two-dimensional geometric figure characterized by its four sides, forming a quadrilateral. What distinguishes a parallelogram is that its opposite sides are not only parallel but also of equal length. Additionally, the sum of adjacent angles within a parallelogram always totals 180 degrees. In the realm of geometry, a diverse array of 2D shapes and sizes, such as circles, squares, rectangles, rhombi, and more, exists. Each of these shapes boasts its unique set of properties. Furthermore, their area and perimeter formulas differ, serving as valuable tools for solving a wide range of mathematical problems. In this exploration,…
Geometry, the realm of shapes and structures, offers a captivating journey into the world of polygons.

Table of Contents: Pentagon Definition Types of Pentagons Properties of a Pentagon Calculating the Area of a Pentagon Perimeter of Pentagon Fun with Pentagons Pentagon Examples Pentagon Definition A pentagon is a two-dimensional polygon with…
Geometry, a branch of mathematics, provides us with the tools to explore and understand the properties of shapes and figures in our two-dimensional world. In this article, we’ll embark on a journey into the captivating realm of 2D shapes, where we’ll discover their characteristics, common types, and real-world applications. What Are 2D Shapes? Two-dimensional (2D) shapes are flat, planar figures that exist in two dimensions: length and width. Unlike three-dimensional (3D) objects that have depth, 2D shapes are entirely flat and have no thickness. These shapes are fundamental in geometry and are often encountered in everyday life. 2D Shapes Definition…
