Revise how to plot a linear equation graph. Learn how to read x and y coordinates from a graph in this BBC Bitesize maths KS3 guide.

The graphing mode is the first open-sourced suggestion to be chosen. It was Microsoft engineer Dave Grochocki’s idea, who suggested that students could use the graphing feature to study algebra.

SummaryIn this paper, we explore Mad Veterinarian scenarios. We show how these recreational puzzles naturally give rise to semigroups (which are sometimes groups), and we point out a beautiful, ...
