Unless you’re a math whiz, “cohomology” is a word you’ve probably never heard. An oversimplified (though still hard to understand) explanation is that cohomology is a tool to extract the algebraic ...
Creating rotationally symmetrical Venn diagrams of increasing size is a longstanding mathematical challenge - now an amateur ...
"I can do Tsurukame-zan (crane and turtle problems), but I freeze up when it comes to compensation problems." is rare to hear ...
' Immersive Math ' is a free textbook site that makes linear algebra, a field of mathematics that studies calculations such as vectors and matrices, easier to understand by providing interactive ...
State what type of graph is shown. Describe the x-and y-axes and what they represent. Write out the points in bullet form. Depending on how important the data points are to the central teaching point ...
Math equations can feel like a banal abstraction without images to make sense of the strings of numbers, letters, and Greek symbols. Consider the Pythagorean theorem, an essential relation in geometry ...
When I look at math problems,I sometimes think, "They probably want to get through this without writing anything if they can.
John Venn – the British logician who around 1880 devised the ‘Venn diagram’ – celebrates his 185th birthday this week. His idea, a brilliantly simple visual aid to understanding logical relations, is ...
Earlier today I set you these four Venn diagram teasers: 1) For each of the regions marked A to D below, think of a fraction that could belong in it, or say that it is impossible. (Each circle ...
