Linear Simultaneous Equations are a system of equations that contain two or more variables. These equations can be solved simultaneously to find the values of the variables that satisfy all equations in the system. A solution is a set of values of the variables that satisfy all the equations in t

Linear simultaneous equations are a set of equations with two or more variables. When we have two equations with two variables, it is called a system of linear equations. Solutions of linear simultaneous equations are the values of the variables that satisfy all the equations in the system.

1. The concept of denominator (positive), index, root and exponent, integers, fractions: Laws of indices are used to simplify expressions with powers or exponents. An exponent is a number that tells you how many times to multiply a base by itself. For example, 2³ means 2 x 2 x 2

Real numbers are a set of numbers that includes all rational and irrational numbers. Rational numbers are numbers that can be expressed as a fraction of two integers, whereas irrational numbers cannot be expressed as a fraction of two integers and have an infinite number of decimals. Real numbers

A real number is a number that can be expressed as a decimal. This includes all numbers that can be represented on the number line. It is a set of numbers that consists of rational numbers (numbers that can be expressed as a fraction of integers) and irrational numbers (numbers that cannot be exp
