Papist's razzle dazzle Stuff

[Papist]

You should know by now that when multiplying by ten, all you need to do is add 0 to the end of the number. But do you know there is an equally easy way for multiplying a two digit number by 11?

I think you will find this razzle dazzle:

Take the original number and imagine a space between the two digits (in this example we will use 52):

5 2

Now add the two numbers together and put them in the middle:

5 (5+2) 2

5 7 2

572 = 52x11

If the numbers in the middle add up to a 2 digit number, just insert the second number and add 1 to the first:

9 (9+9) 9

(9+1) 8 9

10 8 9

1089 = 99x11

If you need to square a 2 digit number ending in 5, you can do so very easily with this trick. Mulitply the first digit by itself + 1, and put 25 on the end.

252 = (2x(2+1)) & 25

2 x 3 = 6

625

Had a razzle dazzle time with son yesterday. Buying fishing rod/reel, Adoration, pizza, topped off with a 22oz Octoberfest beer.

This razzle dazzle watch runs using kinetic energy. It has a micro-generator to generate electricity while you walk.

Razzle dazzle mosquito trap. This thing eliminates insects without poison or zapping. When exposed to heat from an LED, the bulb’s titanium-dioxide coating reacts with the air and produces CO2, which attracts mosquitoes. A fan then pulls bugs into a holding tank. And then you can ship the skeeters to sixpence.

Razzle dazzle screwdriver from B&D. It's called the GYRO. It is the first tool that you can control with gestures. Black & Decker embedded a gyroscope into the handle of the electric screwdriver to control its motor; the farther a user tilts his wrist right, for instance, the faster the motor drives in screws.

Nice. I really like the concept, but how does it set the "zero point"? or in other words, how does it know what amount of wrist turn equals no movement in either direction?

I would think that the position at the start is the zero point mark.
