Zeros Of polynomial

For a polynomial, there could be some values of the variable for which the polynomial will be zero. These values are called zeros of a polynomial. Sometimes, they are also referred to as roots of the polynomials. In general, we find the zeros of quadratic equations, to get the solutions for the given equation. The […]

XXXIX Roman Numeral

In Mathematics, the roman numerals are defined as the numeral system, in which the numbers in the systems are represented using the different combinations of letters. The most commonly used roman numerals from 1 to 10 are I, II, III, IV, V, VI, VII, VIII, IX, X. From these notations, IV represents the number 4 […]

Integers: Word Problems On Integers

An arithmetic operation is an elementary branch of mathematics. Arithmetical operations include addition, subtraction, multiplication and division. Arithmetic operations are applicable to different types of numbers including integers. Integers are a special group of numbers that do not have a fractional or a decimal part. It includes positive numbers, negative numbers and zero.  Arithmetic operations […]

Word Problems on Number Operations

A number is a figure or a value to denote the count or quantity of something. The counting numbers or natural numbers include the numerals 1, 2, 3, 4, etc and are the fundamental of a number. Arithmetic is the elementary branch which studies about numbers, their properties, and arithmetical operations. There are basically four […]

Whole Numbers

The whole numbers are the part of the number system in which it includes all the positive integers from 0 to infinity. These numbers exist in the number line. Hence, they are all real numbers. We can say, all the whole numbers are real numbers, but not all the real numbers are whole numbers. The […]

What is Vector?

A vector is a quantity which has both magnitude and direction. A vector quantity, unlike scalar, has a direction component along with the magnitude which helps to determine the position of one point relative to the other. Learn more about vectors here. What is a Vector in Maths? In maths, a vector is a quantity […]

Symmetric Matrix & Skew Symmetric Matrix

A symmetric matrix and skew-symmetric matrix both are square matrices. But the difference between them is, the symmetric matrix is equal to its transpose whereas skew-symmetric matrix is a matrix whose transpose is equal to its negative. If A is a symmetric matrix, then A = AT  and if A is a skew-symmetric matrix then […]

What is Square Root

The square root of a natural number is a value, which can be written in the form of y = √a. It means ‘y’ is equal to the square root of a, where ‘a’ is any natural number. We can also express it as y2 = a. Thus, it is concluded here that square root […]

What is Prime Factorisation?

Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself. For example, 2 is a prime number which has two factors, 2 […]

What is a Null Hypothesis?

In Maths, Statistics is a concept which deals with research and analysis of numerical data. It sometimes happens that we are not provided with accurate data sets; then we consider the hypothesis. Basically, there are two types of Hypothesis: Null Hypothesis and Alternative Hypothesis. A hypothesis is a consideration or theory based on inadequate evidence […]
