In geometry, the dual snub 24-cell is a convex 4-polytope composed of 96 irregular cells. Each cell has faces of two kinds: 3 kites and 6 isosceles triangles. The polytope has a total of 432 faces (144 kites and 288 isosceles triangles) and 480 edges. (Wikipedia).

Twos complement: Negative numbers in binary
How can we represent negative numbers in binary? There are several ways. This video compares using a sign bit, ones complement, and twos complement. Twos complement is the most commonly technique because it's relatively easy to implement in hardware and it makes addition and subtraction wi

If someone ignored you, was it an honest mistake or a deliberate snub? This math problem demonstrates what most people already know: even assuming most people are fair minded and can make honest mistakes, the odds are the person was unfairly hating. #math #maths #mathematics #probability
