I guess I get that whole internet thingamajig after all. :-)
Thanks mucho to Todd Sieling and the Ma.gnolia gang for fixing the problems I was having with my avatar. He fixed it and contacted me to retry without me having to say anything to them... well directly anyway :-)
Great work to them, and yay, now everyone can see my ugly hidden mug on ma.g woohoo!

The Chicago street artist known as SOLVE (Brendan Scanlon) was murdered June 14, 2008. These are some pictures I took of his artwork, mostly around Uptown and Lake View, in 2006. I had no idea who he was, but I kept seeing his work around the area and always found it intriguing.

I always wondered why this "bus shelter", as I thought it was, wasn't anywhere near the bus stop. I read something yesterday that solved the mystery - this is in fact an old tram shelter, for the trams that haven't been here since the 1930s.

Solving polynomial equations are those equations which contain variables, constants and non -negative integer exponents. We have a general form to write polynomial equations.
So anxn + an-1xn-1 + ...........+ a2x2 + ax + a0 = 0,In this given polynomial form x is a variable and an, an-1, ….. a2, a1, a0 are constants. Here ‘n’ should be positive integer and ‘an’ should not be zero. Let’s take an example of polynomial equations x3 + 7x2 + 3x – 2 =0,Here we can easily see that highest degree of ‘x’ is 3 and all the exponents’ term is non negative integer value. Polynomial equations are categorized according to the degree of Polynomials. So if we are talking about first degree than equation ax + b =0.

I solve sudoku puzzles through a purely mechanical method. I write 1-9 in every box and then cross out the numbers I know can't be in that box. Sooner or later I end up with just the correct number left in the box.

Solving systems of equations algebraically Linear equation can be defined as “Any equation is in the form of ax + by =c is a linear equation with a, b and c as constant and 'x' and 'y' as variables”. Solving systems of equations algebraically can be done by two methods, substitution method and elimination method. In both cases we find the value of the variables in the given equation. We will see the procedure of both of both the method but firstly we will see substitution method.
