Imagine that a variable, say x, represents the number that goes in one of those empty boxes. We can guarantee that x is between 1 and 9 by saying that x solves the equation (x-1) (x-2) … (x-9)=0.

This equation encodes a fact about our game of sudoku, and we can encode the other features of the game similarly. The resulting model of sudoku will be a set of equations with 81 variables, one ...

For example, if you scan a linear equation asking you to solve for x, like “x-4=10,” the results will include links to online tutorials or even YouTube videos explaining how to solve similar ...

Learn how to solve equations with brackets, 𝑥 terms on both sides, and fractions using inverse operations in this GCSE maths study guide.

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician ...

Absolute value equations (AVEs), characterised by the inclusion of absolute value functions in the variables, present inherently non‐smooth and computationally challenging problems that are ...

By implementing AI to solve these equations, large-scale systems can be analyzed effectively in a fraction of the time it would take with traditional methods.

By harnessing randomness, a new algorithm achieves a fundamentally novel — and faster — way of performing one of the most basic computations in math and computer science.
