## Negative Number

A negative number in mathematics signifies the reverse. A negative number is one that is less than zero in the real number system. Negative numbers are frequently used to indicate how great a loss or a shortage is. One may consider an unpaid debt to be a negative asset. If a quantity, like the charge […]

## Integer

The number zero (0), a positive natural number (1, 2, 3, etc.), or a negative integer denoted by a minus sign (1, 2, 3, etc.) are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. The letter Z or the chalkboard Z is frequently used to represent the

## Polynomial

A polynomial is a mathematical statement that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. It is made up of indeterminates (also known as variables) and coefficients. x2 4x + 7 is an illustration of a polynomial with a single indeterminate x. Three-variable example: x3 + 2xyz2 yz +

## Lorenz curve

In economics, the Lorenz curve is a graphical representation of the distribution of income or of wealth. It was developed by Max O. Lorenz in 1905 for representing inequality of the wealth distribution.

## National Assessment of Educational Progress

The National Assessment of Educational Progress (NAEP) is the largest continuing and nationally representative assessment of what U.S. students know and can do in various subjects. NAEP is a congressionally mandated project administered by the National Center for Education Statistics (NCES), within the Institute of Education Sciences (IES) of the U.S. Department of Education. The

## Flexner Report

The Flexner Report is a book-length landmark report of medical education in the United States and Canada, written by Abraham Flexner and published in 1910 under the aegis of the Carnegie Foundation. Many aspects of the present-day American medical profession stem from the Flexner Report and its aftermath. The Report called on American medical schools

## Trigonometry

Trigonometry is the study of angles. It is a branch of mathematics that is used for algebraic solving in geometry. With the knowledge of trigonometry anything from calculus to vector algebra can be solved. Trigonometry is used in finding out the heights of tall objects like mountains, trees, etc. The tool used in trigonometry for this purpose is called clinometer.

## Social network

A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. The study of these structures uses social

## Mathew Baker

Mathew Baker was one of the most renowned Tudor shipwrights, and the first to put the practice of shipbuilding down on paper. The first list of ‘Master Shipwrights’ appointed ‘by Patent’ by Henry VIII of England included ‘John Smyth, Robert Holborn, Richard Bull and James Baker,’ in 1537. James Baker was responsible for many of the designs and the construction of King Henry’s

## Parametric equation

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters. Parametric equations are widely used to express the coordinates of the points that make up a geometric object, such as a curve or surface, in which case the equations are referred to as the
