 Hello, this is Chico. Welcome to math and real life and the language of mathematics. Let me give you a little tour of the site that way you can find what you need as quickly as possible, okay? Now the way this site is set up is basically as an online video textbook and the two most useful sections of any book that you're ever any textbook that you're ever going to come across is the table of contents in the index. Now the table of contents gives you a flow of ideas how the authors decided to share that information with you. So at the beginning of the chapter is usually the more introductory concepts and later on as the chapter progresses harder concepts get attached to it or new concepts get added in that's connected on to the original original topic that you might have started with in a chapter, okay? And that's why the table of contents is super useful and used a lot, right? The index allows you to find the specific topic alphabetically. So it's laid out alphabetically and you know you can go to a certain topic and find out how many different pages reference the certain topic and have a lesson associated with the certain topic, okay? And that's exactly the way I've set up the site. Now the table of contents in the index are located in the left hand column, okay? The table of contents is broken down to two sub-tables. One is the table of contents for the language of mathematics and the other one is table of contents for math and real life and if you click on the button here it'll take you to a little introduction to what each one is and you know the links here take you to the specific table of contents where the information is contained and the index like any other books is laid out alphabetically, okay? And if there's a certain topic that you're looking for you can click on it and you know go to for example if you're looking for exponents and radicals you go to exponents and radicals and there's another folder in exponents and radicals and it contains a whole bunch of pages related to exponents and radicals and from there if you're looking for let's say multiplying and dividing exponents you can click on multiplying and dividing exponents and that'll take you to the lesson that contains the information for multiplying and dividing exponents, okay? Now in the title of a page there's more information than there is in the pull-down menu the pull-down menu here, okay? The title is usually longer because we have more room more space and there's something here called in brackets there's going to be the language of mathematics right or math in real life depending on which table of contents is related to if it's related to the language of mathematics or math in real life The number the numerical number here references either the series for the language of mathematics or the topic for math in real life So for example, this one says the language of mathematics numeral, Roman numeral 2, series 2 So if you go open up the language of mathematics if you go to series 2 you got a whole subsection here for subfolder here for exponents and radicals and the multiplying and dividing exponents is contained in that series, right? The other thing that's important here is the number that I've given the video and the number of references the order in which the videos were taken and edited and loaded on to loaded on to YouTube. For example, this one is Language of Mathematics series 2, video number 46 and usually I'm going to provide a link for whatever table of contents this video belongs to. So this you know there's a link on above the video here which links directly to the table of contents for language of mathematics So you can open that up and go to the table of contents And when you go to the table of contents each series, which is basically you can consider it to be each chapter I've sort of broken it down based on the year that I shot it, right? Or I made the videos and edited them put them on and each series you can click on and go directly to that series So if we click on series one we go to series one if we click on series two we go to series two, right? And we wanted to find out what video number where video number 46 belonged in this on this page Right, so you can either scroll down and see the Roman see the number here And that's what the number is referencing to for whatever series you're whatever video number you're looking for Okay, so whenever you see a video that I've made that we're referencing a certain number Certain video and there's a number usually attached to whatever video I'm referencing This is the number I'm referencing which is this says video number 46 and you know if you go to series two You can click on series two It'll take you directly there and you can find video number 46 and see how the flow of information is being presented, right? So if we go back to the table of contents beside each one is a description So if you go to series two you click on the description It'll take you to a page where it tells you what's contained in the series sort of a summary of You know what you can expect in the series where it starts off with and where it ends up, okay? and if you scroll down there is an image file of The pull-down menu of what you actually have over here Okay, so you can scan this as well and you know see see what's contained in the series if you want to use the pull-down menu Okay the other link beside the specific series for the table of contents is a is a Link that takes you to the exercise of exercises and solutions Which is also a button up top here and if you go to the exercise and solutions if you clicked on that Here's the video. Here's the exercises and solutions for series two, right? Because we clicked on the exercises and solutions for series two So it'll take you directly to there and you know you can take a look at what's contained there And these are each each link is takes you to an image file So for example if you want exponents and radicals Exponents to exponents you go over here. It links you to a page over here And if this is too small you can click on you know a little zoom button either here or here The image will get bigger and there's a little button here You know provide an information on how you go about downloading the The videos if you want to download the videos and have a hard copy of the videos there Okay, and that's basically how the information is laid out for math in real life in the language of mathematics Basically as an online video textbook because you know for a good textbook is fairly easy to find out Where the information is and you know how how you go about learning a certain subjects and you know That's what I've tried to do here make it fairly intuitive and coherent and Make it easy for you to find what it is that you're looking for okay I hope you enjoy your stay here, and if you have any questions or concerns Please send me a message. Okay. I'll see you guys in the next video. Bye for now
