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 […]
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
A polynomial is a mathematical expression consisting of variables (also called indeterminates), coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication. 🔢 The word comes from the Greek poly (“many”) and Latin nomial (“term”), literally meaning “many terms.” Polynomial modeling remains the foundational tool for everything from machine learning regression to aerospace trajectory
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.
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

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 is a branch of mathematics concerned with the relationships between angles and sides of triangles, as well as the study of periodic functions that arise from circular motion and wave behavior. Originating in ancient civilizations for purposes such as astronomy, surveying, and navigation, trigonometry has evolved into a foundational discipline underpinning modern physics, engineering,
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
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

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity. For example, the space occupied or contained by a material (solid, liquid, gas, or plasma) or 3D form. Volume is frequently mathematically measured using the SI-derived unit, the cubic metre. The volume of a container is commonly believed to
