System Architect / Senior Software Developer in Calgary, Alberta. Consulting on various projects, mostly with a .Net or classic ASP background. I've been developing Web applications and Websites for over a decade now ranging from using a propietary markup and ISAPI extensions(C/C++) to Classic ASP(VBScript) to ASP.Net(C# 1.0/1.1/2.0/3.5/4.0/MVC) I enjoy solving puzzles such as Sudoku and mysteries. My previous work involves using various Agile practices,e.g. Scrum and pair-programming, on a CMS project within an IS department's web development group.

I enjoy sharing what I've experienced, learned or think may be worth sharing with the world.

comment Do every math operation derive from sum?
Permutation and functional inverses would be examples of what could be seen as operations that don't directly involve sums but then this depends on one's language.

comment If $0{.}9\ldots$ is $1$, what does that make $0{.}3\ldots$?
How did you prove they were different? While they may not look the same, they can represent the same value: $.5=\frac{1}{2}=\frac{50}{100}$ and a bunch of other ways to express that value.

comment Proof: If $x<y$ and $n$ is odd, then $x^n<y^n$
Note that if $n<0$ you could have a problem as while $2<3$ it isn't the case that $\frac{1}{2}<\frac{1}{3}$ as I recall.

How do you know there will be an even number of numbers between multiples of $N$?

comment Number of ways to place exactly two kings in each column such that no king attacks another
What if n is really small like 1 or 2? Are there still that many possibilities if $n$ is really small?

comment Sum of odd numbers is odd if each of the natural numbers is odd
Expand that expression and note that it ends in a "+1" with the rest having 2 as a factor.

comment Prove proposition on real numbers and inverses.
Consider multiplying each side by $\frac{1}{xy}$ and see what develops starting with $x<y$

comment What is $\frac{9}{3} - \frac{1}{2}$?
3.0-.5=2.5 in my world of decimals. 2.5 would also be 2 and a half or 5 halves.

comment Please explain counting; Discrete Structures
Wouldn't this be overcounting since there is only 1 vowel and not multiple ones?

comment Irrational numbers in between $n$ and $n+1$
Yes though consider whether you'd think the size of this set is countable or uncountable.

comment Two definitions - do they differ?
Note that the expression in brackets is a subset of the initial sequence and thus there could be other terms that don't follow this rule while the second statement is a bit stronger than the first.
