How to learn mathematics Videos

+MakiVerem12345 Just multiply the number with 10 and halve it. 7*5=357*10=7070/2=35

+Uku Sibul I don't get it

+firendable Frauds irrelevant. Comment irrelevant.

+blackxcherry22 yeah right...that's why Scott Flansburg has the world record right?

That's because counting using your fingers vs. counting the actual number of fingers is two different things. Also, I think the whole point of that beginning part was to just describe what made him enjoy math rather than dislike it like a majority of younger people do.

+Whazza . i am like him

+Chillbro Swaggins Even if that's true, you should check out Arthur Benjamin. He multiplied two five digit numbers in his head, which definitely isn't memorization.

No, they didn't. They proved that his mathematical section of his brain (Area 44) is in the area of his brain that controls movement and control. Besides, how would be memorise all those numbers. If he did, why does it matter? A great mathematician would come prepared, even though he doesn't.

+the legendary sword of lore . you are cool

+Atorras 19 because the 9 is a single decimal past the number point of zero. lol

I really like this! I have Never seen it done in such a way like this before! Can u do the same for other numbers? Im trying to teach my son multiply, he started a new school & their doing long devision but he never learned multiplys even in his last school so im looking for the easiest ways to teach him! Anyone have ideas please write to me [email protected] I'd be ever so greatful!!

1 is subtracted by 9 2 is subtracted by 8 3 is subtracted by 7 4 is subtracted by 6 5 is subtracted by 5 And for 6, 7,8 and 9 are the opposite. For expample: if you subtract 4 from 6 it would be 2 that means 6x2= 12 and the last digit would be that number. For 6x3 and all the way to 12 all you have to do is subtract by that same number with the last digits.

Another easier way to solve the 9x tables lets say we had 6 x 9 yeah?! the answer is 54 so whats the easy way? Always subtract the number on the left by 1 which - 5 then subtract the answer that you got from subtracting the 1 from the 6 which in this case is 5. so 6 - 1 = 5 5 - 9 = 4 6 x 9 = 54 and you can do the same with the rest :) enjoy

Put a plus sign between the 2 numbered answers. It will always equal 9. 5x9=45 always minus 1 from the number you're multiplying the 9 by (the 5) 5-1=4 then ask yourself, what plus 4 equals 9 that's 5.,, 4+5=9 the answer is 45. Lets try 9x8=? Minus 1 from the number you're multiplying the 9 by 1-8=7 what plus 7 equals 9? 2,, 9x8 is 72.

Look , iknow that when I was in Grade1 but i dont use them because its not an easy way to do , it makes you little harder to do it , unless your writing it by nine its easy ,,, but when you memorize all by 9 in your head , its so much easier to do ..

I will give you the 8's subtract 2 by the last digits with the answer. 8x1=8 8x2=16 8-2=6 8x3=24 6-2=4 8x4=32 4-2=2 8x5=40 2-2=0 8x6=48 8 8x7=56 8-2=6 8x8=64 6-2=4 8x9=72 4-2=2 8x10=80 2-2=0 8x11=88 8 8x12=96 8-2=6 and keeps on repeating.

Silly Americans, you think your way is the only way. Look at the way 9 is when you type - that's exactly how how he wrote it! 9999999999!! Where did American q even came from? I think it looks like 'Q' :oP

i have a better one you have ten finger if want to know what 9x3 is lower your thrid finger this leaves 2 figers to your left and 7 fingers to your right so you know the answers is 27 works for up to 10

Silly Americans, you think your way is the only way. Look at the way 9 is when you type - that's exactly how how wrote it! 9999999999!! Where did American q even came from? I think it looks like 'Q' :oP

instead of using fingers i do the math in my head, for example, if you have 9 x 5 i would subtract 1 from 5 and get (4), then subtract 4 from nine ande get (5), your answer is 45. easy as pie. mmm pie.

also all your ans should add up to 9 ....... 9 x 5 = 45.... 4 + 5= 9 or 12x9= 108.... 1+0+8=9 if you can learn the 2,5,6,9,10 ,12 and memoriz them u can always count up to or back to easyer

I would call this steps to learning how to fondle numbers on maximum digits of two. This technique doesn't work for all multiples of n (which is much more mathematics related)... lol

You can also do this with 5, 6, 7 and 8 heres how. For 5 subtract by 5 For 6 subtract by 4 For 7 subtract by 3 For 8 subtract by 2 And of course 9 you subtract by 1

or you could just memorize it and understand the concept of multiplication instead of adding in numbers without realizing it's concept or understanding it

THIS IS SO EGACATION BEL GOOD FOR OUR BRAINE FOR OUR SISTEM THIS IS NOT STUPID YOU GUYES ARE SICK AND STUPID

That dude's "9s" look like a "g" and I love the way he writes his "8's'. His accent is more annoying than his handwriting tho.

omg that is so easy. i made flash cards but i should have watched this first.thnxs is it the same with the 3,4,5,6,7,8,?

thats great. I just noticed something. If you add the numbers in the answer, they all equal 9. OHHHHHHHHHHH

and also, if you add the digits of each answer together, you always get 9. (ie. 1+8=9, 2+7=9, 3+6=9)

@ytvration Just this one there is another wat to remember all the numbers = 9 eg 1+8=9 7+2=9 see :)

+Akshay shinde it works only with 10^n-1.i.e 9 , 99, 999, 9999, 99999 etc

ok

+shiva manoj Those multiplications have not been mentioned in the Vedic texts .but such multiplications can be done by other methods try searching Crisscross and vertical multiplication.

Thanks Mr pawan

+vishwanth somasundaram 584 - 1 = 583 /58399 - 583 = 57816 ans 584*99 = 57816 sutra"s worklearn every thing in vedic maths please contect me 9785289060 thanks

+Pruthviraj Ajjavara hello will you please tell me if somebody is good at vedic maths is it possible for him to do well in school maths as well as in higher class maths.

+Mr. Lolz That is because you do not have the fundamental skills required to work at this level of mathematics. Unfortunately too many students are like this. I assume you have 2 years until you are college age. There is still enough time to develop fundamental skills.

+bighands69 The question that I was raising is how his natural-language-metaphor approach scales to any more-complex branch of mathematics. At some point, the entities of discourse aren't 'like' things in the world of everyday experience, for instance well-typed terms in the Calculus of Constructions, and it's not clear that there are natural-language metaphors that are even remotely useful in doing anything other than leading people astray.I'm agnostic regarding whether his approach works for arithmetic; I'm just curious how he (or others) would try to scale it up to more-abstract branches of mathematics :~}

+K.D.P. Ross Mathematics is a mechanism to communicate certain forms of logical constructs. There are grey areas in mathematics that is where there is philosophical debate. But as a language it can hold true. Now it would not be the most efficient language for people to communicate their basic interactions upon but it is still possible. It is more than a metaphor to say mathematics is a language as it can literally be used as a language.

+BlackMarluxia Language has abstraction within its structure as well. Words like letters can fit into those construct just as numbers fit into the likes of a pascal's triangle. We can form procedures that in effect can contain different value sets and even the procedure its self can become part of a greater abstraction which also happens in languages. What can be called an apple in English can be know as Pomme in French or if we desire in mathematics ((125^2)/4) It is completely up to the interpreter as to what they define. Mathematics in its self can become a language but it depends on our classification of language.

+mattcline1226 I suppose what he is getting at is that mathematics being taught in schools is being over complicated. He is trying to say that with better communications skills using every day language we could learn more mathematics than what you are learning. I have my own take on things. I believe we are doing too much high level mathematics in schools and the kids that are coming out of school have really missed out on the basics because of this.

One way is to first explain why the "apple + apple" approach works is because you're adding quantities that have the same unit. Then, you proceed to ask "So, how do you add one one-fourth plus one one-third?" Hopefully, the kid you're teaching would realize that the trick is to make the unit of the quantities the same. Then, you teach how.

+teckelred That actually makes sense. 

+darkheart1721 Take 12 eggs. Get them to understand that 1/4th of that is 3 eggs. Likewise, 1/3rd of that dozen is 4 eggs. Therefore 1/4 + 1/3 = 7 out of 12 eggs, i.e. 7/12.

+darkheart1721 You convert the fraction to have the same denominator. 1/4 becomes 3/12, and 1/3 becomes 4/12. Now take the same approach as in the video.

+Michael Col I'm just going to take this idea and run with it. One way to explain fractions would be like this:You have three apples and two oranges. What do you have? You don't have five apples, and you don't have five oranges. Well, you need them to be the same kind of thing. So, you turn them into something more generic: three apples are three fruits, and two oranges are two fruits. Then you can add them. You have five fruits.Now, let's try the same thing with fractions. You have three fourths (3/4) and two thirds (2/3). How many do you have? First, turn them into something more generic: three fourths is nine twelfths (9/12), and two thirds is eight twelfths (8/12). Now, you can add them. You have seventeen twelfths (17/12), or one and five twelfths.Well, that's how I would teach it.

+Michael Col Although...how do you convert apples to oranges xD...?

Hmm, lemme try. Your kid has to be able to convert between different units. If they understand that saying 1 foot is the same as 12 inches, then they should understand this.---------------------"You can't add the numbers if they are different stuff. What is 1 apple + 1 orange?"Hopefully they say that it's not possible."Well we need to add 1 third to 1 fourth. Remember that 1 third is equal to 4 twelfths. Also, remember that 1 fourth is equal to 3 twelfths.""You have to change the numbers to twelfths before you can add them."Hopefully they get this result.1 third = 4 twelfths.1 fourth = 3 twelfths. 4 twelfths + 3 twelfths = 7 twelfths.------------------------Granted, it'll most likely be better to teach them fractions like we usually do. Like you show them somes fraction of a pie, and teach them how to add that way.

Arithmetic deals with numbers and math is based in theory of whats going on in much more complex things.

It is still a branch of math on its own right.

+WongFu4Lyfe Arithmetic is to math as spelling is to writing a novel mate.

And what you think arithmetic is? It's one of the most fundamental and oldest branches of mathematics.

+Jordan Young yeah, its like you don't really need it in "statistics," and "coding"

Yeah its not like "engineering or "economics" are full time careers. Oh wait.

+Katelyn Stewart I can see you are fat in your picture, quite fat. You keep poking a fire and then getting upset about it. Again - that's YOUR choice.

+vladlashing I'm sorry???? You accused me of being fat because I didn't agree with you? How exactly does that make sense?

+Katelyn Stewart nope didn't miss the point. But I have points of my own which you dont like because you too are fat. Too bad. Reality is what it is whether or not you choose to live in denial. You are picking fights and now are going to cry I am sure. Again - to bad. Its your choice.

+vladlashing I'm pretty sure the parody wasn't supposed to be about women being fat, which none of these models really were. They weren't size 2, but they were by no means "trailer park fat catladys." Your tiny brain missed the point, here.

+Anna M Foster I know this video is a joke but believe me some people really are that stupid.

But the video is satire... It's not real

Well the video is satire so... It's a joke.

It's a parody! Pipe the fuck down (to quote Jenna Marbles).

Satire

+Ken Narcisse she is the only pretty one to look at in that lot and her anger in a Clara kinda way was kinda sexy lolat least on a level of sophistication she wont tell them to learn vibrations
