Some people insist on stating the obvious.

That much math will really get your mind drifting!
Makes my head hurt.

Agree, but math isn't high tech. Most people understand when you want to find the answer to a problem, certain basic steps should be followed. Let me give you an example:
[(3x^2-27)divided by 4)] times[ 8x^2) divided by(9-3x)]divided by [(x^2+3x) divided by 6]
Ok, to find the answer we can invert the third fraction then multiply straight across like this
(3x^2-27)(8x^2) 6
-------------------------------------
4(9-3x) (x^2+3x)
but first we can factor and cross cancel
(3(x-3)(x+3)(8x^2) 6
--------------------------------------...
-12(x-3) x (x+3)
after we cross cancel we get
=-12x
Or, to make it simpler, we can start by inverting the last fraction and multiplying:
3x² - 27 .. 8x² ....... 6
----------- * -------- * ----------
.... 4 ...... 9 - 3x . x² + 3x
Now you can do some factoring and canceling:
3(x² - 9) .. 8x² ...... 6
----------- * -------- * ----------
.... 4 ..... 3(3 - x) . x(x + 3)
You can cancel the 4 with the 8, remove the 3's and the x's.
(x² - 9) .... 2x ........ 6
----------- * -------- * ----------
.... 1 ...... (3 - x) . (x + 3)
Now x²-9 is a difference of squares which can be rewritten as (x - 3)(x + 3):
(x-3)(x+3) .... 2x ........ 6
-------------- * -------- * ----------
....... 1 ...... (3 - x) . (x + 3)
Cancel the x+3:
(x - 3) .. 2x .... 6
------- * -------- * ---
...1 ... (3 - x) .. 1
Now notice if you factor out a -1, you have 3-x which will cancel:
-1 .. 2x .. 6
--- * ---- * ---
.1 ... 1 ... 1
Multiply across and you get:
-12x
So you see, there isn't really anything high tech about it. It's just math and it's just plain fun.
You are an evil, twisted person. When I was in school, right after the War of 1812, people like you were sometimes found in their lockers months later.

This thread does seem to be going adrift. I've been expecting that.

After reading all the replies to the OP, I get the drift -- so to speak.

He who goes forth with a fifth on the fourth might not go forth on the fifth.

Now that sounds like a voice from experience.

So Geddylee; What exactly is your problem? If so, consider it solved.

Was it a Scottish Golf or Cinco de Mayo reference?

My tuxedo cat got out and came back the other day. Some weird person shaved her belly and private parts. Sometimes you just gotta wonder who all is out there. Frank

Mouse gun.
Never really been a fan of mouse guns but this is funny! Does the clip hold 10 rounds to take care of the cat?
