Decimal Multiplication by Power of 10 Multiplying decimal numbers by 10, 100, 1000…… Multiply any decimal by any power of 10 or 10, 100, 1000, we just move the decimal point towards the right as many places as the number of zeros in the power of 10. When we multiply any decimal by 10, we […]
Read More →Exponents and Power Rules In this chapter we will learn about exponent and power. These are very large numbers, and difficult to read, and compare. To make these numbers easy to read, compare and understand we use exponents. Exponents Definition: When a number repeatedly multiply by itself, we raise it to a power. This is known as […]

The terms must have the same variables […]

Read More →Order of mathematical Operations The four basic operation in mathematics, as everyone knows, are addition, subtraction, multiplication and division. These basic operations are used in algebra with numbers or letters or combination of both. A number multiplied by a variable, a number or variable is called a term. An expression is combination of such terms. Example: In […]
Read More →Like and Unlike Algebraic Terms Similar or Like Terms In an algebraic expression, like terms are terms that have same variables with same exponents and only the numerical coefficients of like terms are different. The terms must have the same variables and the same exponents. 3x, 7x, 8x, 12x, x, -4x, -9x all […]
Read More →Addition and Subtraction of Polynomials Addition of polynomials means we simply add the like terms. so, what is “Like terms”? Like terms are terms that have the variables, and powers are same, and coefficients of terms can be different. Example: 1. Yes 2x, -5x, 11x, […]
Read More →Linear Equations in two Variables If the equation has more than one variable and the highest power of variable, appearing in the equation is 1, such that variables are not multiplied each other then this type of equation is known as “linear equation in two variable”. Some examples of linear equations in two variables are, […]
