Introduction to the concept of Symmetry The word “symmetry” is frequently utilized in daily life; instances include the symmetry of butterfly wings, architectural designs, and more. Do you recognize symmetry? When a figure can be folded into two identical halves, we say that it is symmetrical, and as a result, this phenomenon is referred to […]
Introduction The relationship between a number and its square root is important to understand. Squaring a number means multiplying it by itself, while finding the square root of a positive number involves finding the number that, when squared, results in the original number. For example, if the square of a number p is q, then […]
An Introduction The value of a variable determines the value of an expression. By substituting the variable’s value in the expression and utilizing mathematical procedures, the expression is made simpler. The expression’s value is the outcome that is ultimately obtained. A whole integer, rational number, decimal number, or real number can be the value of […]
Introduction Multiplication is one of the basic mathematical operations used in algebraic expressions. We can classify algebraic expressions according to the number of terms they contain, such as monomial, binomial, trinomial, quadrinomial, or polynomial. A monomial expression is a one-term algebraic expression that contains a variable and its coefficients. A monomial multiplied by a monomial: […]
Introduction In every area of our lives, we are surrounded by numbers. Factors and multiples are also commonly used in our daily life. We use factors when we want to arrange things differently. For example, arrange books in rows and columns, group children in different ways, etc. Let’s consider the number 112. 112 can be […]
Introduction No matter how many sides there are in a polygon, the sum of all exterior angles is \({\bf{360}}^\circ \), and the sum of all internal angles is \(\;\left( {{\bf{n}} – {\bf{2}}} \right){\bf{180}}^\circ \) given that the number of sides is n. Shapes are \(2 – \) dimensional and \(3 – \) dimensional; we have […]
Introduction There are several instances when ratios and percentages are employed. The proportion and ratio ideas you acquired in earlier sessions are still fresh in your mind. On a milk packet, several milk components are listed in percentages. A certain ratio of finger millet flour and wheat flour is used to make ragi bread. To […]
Introduction We come across several items of various shapes and sizes in our daily lives. Many items have three sides, whereas others have four, five, and so on. Some forms have equal sides on all sides, whereas others do not. Consider our laptop screen, deck of cards, tabletop, chessboard, carrom board, and kite as examples. […]
Introduction An expression made up of variables, constants, coefficients, and mathematical operations like addition, subtraction, etc. is known as an algebraic expression. Algebraic expressions have several uses, including describing real-world issues and solving various and difficult mathematical equations, calculating income, cost, etc. There are two categories of words in algebra: like terms and unlike terms.
