Microsimulation methods are used to identify the contribution of tax and benefit reforms to the significant growth in UK income inequality since 1979. The total effect turns out to depend crucially on ...

The future of math education will begin with the divorce of a very long-term marriage between math learning and grade-level instruction. “The Future of Math,” my chapter in School Rethink 2.0, ...

This book outlines the modern theory of functional equations and inequalities in several variables. It consists of three parts. The first is devoted to additive and convex functions defined on linear ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

Graphing an equation is an essential skill in mathematics, as it helps us visualize the relationships between variables. There are several techniques that can be employed to make graphing easier and ...

ABSTRACT: This paper presents a new dimension reduction strategy for medium and large-scale linear programming problems. The proposed method uses a subset of the original constraints and combines two ...

2. Graphical Method: The graph of a pair of linear equations in two variables is represented by two lines. (i) If the lines intersect at a point, then that point gives the unique solution of the two ...

“These math books, they were doing woke math. … Two plus two equals four, right? Not two plus two equals, well how do you feel about that, is that an injustice?” Despite the humour, though, DeSantis’s ...
