Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...

We consider a class of iterative algorithms for solving systems of linear equations where the coefficient matrix is nonsymmetric with positive-definite symmetric part. The algorithms are modelled ...

Methods for solving symmetric indefinite systems are surveyed including a new one which is stable and almost as fast as the Cholesky method. Journal Information SIAM Journal on Numerical Analysis ...

Learn about and revise how to solve equations using the balance method with this BBC Bitesize GCSE Maths Edexcel study guide.

GCSE AQA Solving linear equations - AQA Solving equations Forming, using and solving equations are skills needed in many different situations. From balancing accounts to making sense of a mobile ...

Research suggests that word problems might be easier to grasp and more beneficial at the beginning, rather than the end, of a math lesson.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The MIT algorithm mimics this nonlinear phenomenon on a quantum computer, using Bose-Einstein math to connect nonlinearity and linearity. So by imagining a pseudo Bose-Einstein condensate tailor made ...
