hyperbolic geometry
Hyperbolic geometry is an example of a geometry where the parallel postulate fails in the sense that given a line L and a point P not on that line there are infinitely many lines through P that are
parallel to L.

How to Test Vector Types in R
R contains a set of functions that allow you to test for the type of a vector. All these functions have the same syntax: is, a dot, and then the name of the type.

A Strategy that Fosters Translating Between Multiple Representations
Mathematical communication (Schoenfeld et. al., 1992, Koedinger & Nathan, in press) is increasingly seen as a goal for students, and in particular, translating between algebraic (e.g. "m/s+h"),

Subtraction - Properties
agreement associative closed example
It matters very much which of the two parts of a difference are named first. Taking $500 from an account with $300 in it is very different from taking $300 from $500. For this reason, subtraction is
not commutative: a - b does not equal b - a.

Here's a nice challenge that I made up thinking about compressing data one night...
Print out a number that you can read within it:
The numbers 1 to 20(easier) or 1 to 99(very hard)
→Can be read forward or backwards and use same numbers
eg. 123 you can read 1,2,3,11,12,22,21,23,32,33
