Hello, I'm Martin And I'm An Algebraic :-)
If you're sat next to me on a plane you'll probably notice at take off and landing I do algebra puzzles. You may not have heard of the term "algebra puzzles" before and perhaps think the juxtaposition of the two words to be odd, but I think it apt...
(You may also think this whole post to be showing off, but that's a risk I take in sharing a passion I have.)
A classic problem... [More]

Factorise - For Your Eyes
As you might know I like maths, particularly algebra.

Hello, I’m Martin And I’m An Algebraic you do.) If there’s one thing I would be doing if I weren’t doing this [1] it might be teaching maths - but it would have to be at a level where algebra and calculus were substantial topics.

Another Neat Piece Of Algebra - Series Summation
Here's another neat piece of algebra: A technique for summing series. You know what b - a + c - b + d - c is. Right? Suppose I were to write the same sum as: (b - a) + (c - b) + (d - c) The answer is still d - a. Right? Now, suppose I re-label with s 0 = a, s 1 = b, s 2 = c and s 3 = d. We end up with: (s 1 - s 0 ) + (s 2 - s 1 ) + (s 3 - s 2 ) This is actually pretty scalable terminology as you... [More]
