INTRODUCTION:
http://www.chycho.com/?q=Introduction_Instructions

During the last few years the education systems in Canada and the United States has been eroding. Students have been crammed into larger class sizes while the quality of teaching has deteriorated, in large part due to a lack of funding from local and federal governments.

John Ralston Saul, one of Canada's most celebrated authors and essayist, has warned us that "Canada's democracy... is eroding with every dime deducted from education budgets."

I have stated previously that I believe "as a collective we must understand that democracy can only exist in a society with an educated populace, and the right for self-governance can only be obtained through knowledge." I also believe that as long as the Internet remains Neutral, we, as a global community, can make a difference. We can fill the gap left behind by our governments and be proactive in educating our children

Sharing our communal experiences and knowledge is the essence of the Internet and chycho.com is proud to be a part of this movement. The information contained and conveyed through this medium is what will shape our future, and this site was created to represent a unique personal perspective and to contribute in bringing about positive changes.

As a result I have decide to produce instructional math videos to help those that want to improve their abilities in communicating in the language of mathematics. The videos are available on Chycho TV Located in the top right corner of http://www.chycho.com. Even though these videos are geared towards high school students, they will also help those in elementary school and those that are struggling with certain college and university courses.




The format of the videos is as follows: Lessons are in large part self contained and most have exercises which should be completed before proceeding to the next lesson. To help people understand a specific topic I have included answers to the exercises and a video showing how I solved the problems. Hence all exercises will have a video showing the exact steps taken to get the correct answer. Please make sure that you view these videos if you are having difficulty solving the problems.

During the next few weeks and months, possibly years, I hope to be able to provide a vast library of resources for those that wish to finally understand the language of mathematics.

If there are certain areas that you are having problems with or wish me to discuss further then please send me a message or post a comment at my website. Even though I can not guarantee that I will be able to properly represent a topic I will try my best to produce a lesson if there is strong enough demand for a specific topic.

I hope these videos will help people learn how to communicate in the language that we have chosen to understand the world around us in a scientific manner, in the language of mathematics.

Best

Chycho, since your name sounds like "Ciccio", which in italian is short for Francesco. I wonder if you're name is related to Italy in some way.

Also, I'd like to ask you if you've... cleaned up all those walls after your explanations. :-D

I love your videos, I love the way you explain math.

Please keep up the great work you're doing.

Greetings from Sicily!

I've been "asked" a couple of times to clean the walls, and have done so, but in general I try to be in and out of a place as quickly as possible ;)

glad you like the vids, greetings for Vancouver :)

[bytedildo]

can you do some advanced math?

[chychochycho]

I am and will continue to do so for quite some time. Check out the videos on my youtube channel and the links to the table of contents.

I think you meant to say 4 minus 2 and 15 minus 9

[chychochycho]

that i did, thank you :)

Basic math skills are slowly being replaced by basic calculator skills. Now they're still teaching though, I'm just think Chycho added these lessons for any younger viewers or for adults coming back to math after several years. nothing wrong with reviews.

I learnt that at school. It's not common these days ? OMG !!!

[rezek71]

I am sooooo confused?? I learned all this in like first grade?? Are they NOT teaching this any longer in schools?!! WTF?!!!!!

These algorithms aren't conducive to mental computation. Personally, I couldn't subtract using the methods you describe (I would either do it mentally or with a calculator). How would I subtract 257 - 29 mentally? I'd subtract 257 - 30 and then increment by one. Alternatively, for bigger numbers I might "simplify" both numbers and adjust the result as needed.
