After finishing my high school I almost forgot what mathematics are for the last 5 years. Seeing this videos brought me back to the good old days.. thanks Mr.Woo.. you are an amazing teacher. I can see the passion in your teaching style. hope your students appreciate that. keep it up.. AND KIDS ENJOY IT WHILE IT LASTS
Is it bad that I instinctively raised my hand when he said "Does anyone have any ideas?"? Also; I have this on my second monitor while gaming and still look over when he said "Everyone look at the board.".
I’m 38 hrs old with a busy lifestyle..I decided to go back to school.To my amazement , I realised I forgot everything I learned in school. This guy is the best teacher I have discovered to revise everything I have learned.
Dear Eddie today I was explaining to my 11 years old son why the multiplication of two negative numbers results in a positive on a number line, he was taught in school that multiplication is repeated addition, and he asked me to explain it in this way only, I couldn't, I told him that that is true only for positive numbers. We ended up arguing and stopped talking to each other. Can you explain it your future video. Remember he is 11 year old.
that moment when ure a Civil Engineering graduate and an incoming AI masters student, but you find these videos very amusing and interesting because u never learned MATH IN A FUN WAY!
Mr. Woo can you please upload video on factorization of algebraic expression by division method. and square root of algebraic expression by division method. I will really appreciate it.
Honestly i learn more when watching videos online. I never have to worry about my surroundings during class and whenever i don't understand something i can always simply go back.
Mr. Eddie woo I am from India, i like ur teaching skills, so i think u can explain this correctly. What is the correct anr of 6/2(1+2) Somebody says 9 others sayed 1. But which one is correct way to solve this, it's really confusing.??!!
The answer is 1 use the BODMAS TECHNIQUE first bracket then open the bracket then division then multiplication then addition then subtraction 6/2(3) 6/6
dinesh killer Well, the notation is false and unclear so you can't know the answer. You have to write this as a fraction, then it's clear whether (1+2) is in the numerator or in the denominator.
My school uses these lectures in a fully digital "web school" package. I paid over 3k for this package so I could get the math and physics diploma I need for CS. It's literally just a sorted catalog of this guy's videos + some self-recorded garbage with poor mic quality, bad explanations, and answers drawn with the mouse in MS paint... I'm at least really grateful I don't need to listen to only the self-recorded lectures provided by my school for a year. But they did charge me over 3k USD for a selection of publicly available videos... I want to add; even though the school I choose suck. This guy is really awesome, none of my previous teachers can even compare! If you are willing to spend some time looking you can learn everything you need from high school math from just this channel.
6:54 - I'm trying to relearn this stuff ready for uni and where the hell did that 1 come from? I work it out 5a(-4a^3) then realised my mistake but then got 5a(-4a^2) i have no clue where that 1 came from
@D4RK AuraZz Well, by taking out the 5a, you're left with two square numbers inside the brackets. 1 is 1^2 and 4a^2 is 2a*2a. This means you can rewrite the whole expression as 5a(1+2a)(1-2a)
The number 1 is a trivial factor. Any expression can be multiplied by as many 1's as you want, without changing anything. An application of this, is unit conversion factors, where to change a number from one unit to another, you multiply by 1 in a fancy way. For instance, given 2500 meters, if we want kilometers, we multiply by 1, which equals 1000 meters/1 km, which gives us 2.5 km. Another reason why you'd multiply by 1 in a fancy way. In calculus, there's a method where given an integral of x/(x^2 + 1) dx, it is of interest for 2*x appears in the numerator, for the method we'd like to use. Since it doesn't, we can make it happen, by multiplying by 1 in a fancy way, since 1 = 2/2. This allows us to produce 1/2*integral 2*x/(x^2 + 1) dx. If you aren't familiar with calculus yet, don't worry about it, just observe how this is a useful technique for hammering an expression to look like the form you want. If you care, the solution ends up being ln(|x^2 + 1|) + C. In that example, he factored it to 2*(24 + 5*a). If for some reason, we REALLY WANT a to appear without a coefficient, we can continue factoring it as 10*(24/5 + a). You could also factor it as 24/10*(1 + a/10), if you wanted that form as well. It doesn't look as clean and simple, so it is usually preferred to only factor enough to still leave constants as whole numbers, where possible.
If I had a teacher like him I wouldn’t even miss a class

You can factorise 5a(1-4a²) further to 5a(1-2a)(1+2a)
BeeBee Gun im assuming the grade level hes teaching at has yet to reach that

Ooo, difference of 2 squares. I missed that

and you can further factor??? LOLALLALASGAHAHHAH

Thank you sir for making your videos I have a maths test tomorrow morning I I couldn’t understand factorising anything until now YOU ARE A LIFE SAVER
I loved watching this video. JESSICA STOP INTERRUPTING THE CLASS.
hahahahaha
I literally get goosebumps, from his skill of teaching. Wow!
This is awesome! My maths teacher just gave us a puzzle worksheet and expected us to figure it out.

same lol in my school we're not aloud phones not even talking about computers
hey..i love the way he teach..very friendly yet clear..thank you for sharing eddie :)
I dont understand this in my whole but after watching I learn the whole concept this teacher is brilliant

Tell me about it. My master's degree is in EDUCATION, I'm a high school teacher, and I get a kick out of watching him. Lol!
Mrs. Morris hahaha!
there is no way to learn math in a fun way bffr
Mr. Eddie, you are putting us teachers to shame mate, I recon I'll just play this in my class instead of teaching it myself. Keep it up!
Mr. Woo
can you please upload video on factorization of algebraic expression by division method.
and
square root of algebraic expression by division method.
I will really appreciate it.
I wish I had teachers like him
1-4a^2 definitely is factorable, but maybe later❤
Learning This in school and I think this is Grade 8 or 9 but I’m in Grade 7 and this is pretty interesting
Yes, it is fift grade question.
But , Eddie woo sir is really better teacher.
Honestly i learn more when watching videos online. I never have to worry about my surroundings during class and whenever i don't understand something i can always simply go back.
Awesome presentation
BEST Teacher!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I love this guy.

What is the correct anr of 6/2(1+2)
Somebody says 9 others sayed 1.
But which one is correct way to solve this, it's really confusing.??!!
The answer is 1 use the BODMAS TECHNIQUE first bracket then open the bracket then division then multiplication then addition then subtraction
6/2(3)
6/6
My calculator shows 1
When i put this 6÷2(3)=1
But my mopile calculator shows 6÷2(3)=9
Confusing??!!
It means my casio fx-911ms calculator is wrong??
@UCD5dv-1KUgDk9YuI3GBIpog wrong
6/2(1+2) according to bodmas will go like
6/2(3)=
3(3)=
9

I just realised it could be either.
watching this is more fun than watching musty, dream or any gaming videos

When he said take away a -1 why did he do -12 please respond quick
thanks man doing better than my teacher

if i had a teacher like him i would be so happy ima turn into einstein
Omg! Love the way he teaches. 😍
If your in love with him just propose

Sir what happen when log zero to the base zero????????
Please tell me !!!!!!
There cannot be a zero in log.
But why sir
But in a video, sir Explane the (0^0=1)
@@arvindgupta7798 There is no consensus on the value of 0^0, but in calculus, it's generally assumed to be undefined.

another question what is 11de2f?
the 2 is squared btw
bruh i learned more in 13 mins than 3 hours

1 times anything is itself. 5a(1 + 0)= 5a
thank youu sir !!
When you are ahead of the class and see that in example two you can use the difference of two squares
@D4RK AuraZz how to use the difference of 2 squares?
@D4RK AuraZz Well, by taking out the 5a, you're left with two square numbers inside the brackets. 1 is 1^2 and 4a^2 is 2a*2a. This means you can rewrite the whole expression as 5a(1+2a)(1-2a)
