Your voice is relaxing
Your casper the ghost
Im jasper the child :p
Thank god I’m not the only one that thinks that

I haven't been able to attend my online classes and I was frustrated on how to answer the questions, but then I found your videos and it completely saved my life.🥳
Bought your course! I'm working through it slowly. It's straight forward, just like your UA-cam videos. I love that it's available for life after one purchase---no subscriptions, no hidden fees.
Bless your good heart! I have an exam coming up tomorrow and I didn't listen to the teacher explaining, so you've really saved me 👍👍
I want to thank you so much for these videos. I was never good at math in high school as I had a lot of stuff going on at the time and ended up giving up on it when I felt like the class was moving faster than I could even read a question. I had bare basic math skills so about a month ago I have been dedicating every day when I am not working to learning math from the ground up again. I am on the last chapter right now of a Algebra Textbook, it was quite long but I got through it. These videos as well as the books I have found online have been a great resource to sharpen my math skills. Thank you.
thank you you are very clear even for people like me who believed that maths is too difficult to learn but now it's not
You saved my life . Thank you so much for your help 💗

I fuckin love this guy always comes in clutch wit last minute studying for a test
Can I ask? What if the equation is (0.15t)(-0.2d), what would be the answer? Its kinda confusing for me.
Thanks sir u really helped me,I have an exam coming up
My Algebra teacher is out getting knee surgery and the sub is clueless, so this helped me a lot.
Godbless , i really like it , 😊, your video help me to understand what math is
That website is good for asvab test on mathematical and arithmetic??? The one you just showed on the vid
Man i had and important quiz yesterday i got the results and i aced it thank you so much you are the best
I turned this on to help me sketch-
how you put it negative ?????
I really find this helpful thank you
This guy is a legend why isn't he verified?
Thx that rlly helped me 👍🏼
im an absolute academic weapon because of u 💯💯
When the next thing you're learning in class is right here. Stay ahead of the game people.
What about 8² / 8⁴?
Can you guys help me?
when youre diving, you subtract. I learned this song in math class. "Like base. Like bases. If you multiply you add, if you multiply you add, like bases. like bases. if you divide you subtract, if you divide you subtract, like bases. like bases. If its a power then you multiply, if its a power then you multiply, like bases. like bases. its kinda cringey but if you repeat it, it will actually help you. Anyways... so "if you divide you subtract" (in the song) you subtract the exponents, 2-4 = -2 . So what you get is 8-² (8 to the negative 2 power idk how you do the little subtract symbol) and if you dont want a negative exponent, you take 8-² ( 8 to the negative 2 power) you get the reciprocal of it. think of 8-² as 8-² over 1 or 8-²/1 and take the reciprocal which is 1/8-² and change the exponent to a positive so the answer is 1/8². I am very bad at wording so just let me know if you are still having trouble!
when you divide monomials you separate the power and the number. Basically just subtract the power
Ex. 7⁴ / 3⁹
9 - 4 = 5
7÷3 = 2.3
i might be wrong
Canadianbutt 275 uhh idk what youre trying to do...

Great lesson! Quick question though, why'd you remove the variables at around 6:44?
Hi there! If you're referring to how the variables on the bottom were removed that's because they went from the bottom of the fraction to the top of the fraction. You can see it on the right-hand side as negatives. (x^7 * y^9)/(x^4 * y^5) = (x^7-4 * y^9-5) Which simplifies to (x^3 * y^4). I hope this helps! Small clarification, variables in the denominator with exponents are equal to the variable to the variable on top with a negative exponent. For instance if you start with (1/x^2) this is equal to (x^-2) similarly 1/(x^4 * y^5) = (x^-4 * y^-5). To put all this together for the example shown the process (35 * x^7 * y^9)/(63 * x^4 * y^5) = (5 * 7 * x^7 * y^9)/(9 * 7 * x^4 * y^5) notice how there's a 7 on top and on the bottom? We can cancel those out. (5 * x^7 * y^9)/(9 * x^4 * y^5), recall that variables with exponents on the bottom become variables on top with a negative number. ((5 * x^7 * y^9) * (x^-4 * y^-5))/9 then multiplying across those variables results in (5 * x^7-4 * y^9-5)/9 which finally becomes (5 * x^3 * y^4)/9.
I have a question in here 2:02, how did you get 8? I don't understand please help.
Since the answer before that is 2 to the power of 3, you simply multiply 2 with 2, 3 times since the power defines how much you'll multiply by itself (sorry for bad english)
Test about this is tommorow. Wish me luck! 🤞
Tnx I learned from you
this was soo useful thanks
very helpful
In the multiplying part, he says multiply the exponents but then he adds them so I’m confused
2:26, how did you get the -4
Jibriel Doria 7 is larger than three by four, making it a negative four
He took away 7 digits from 4 making it go into the negative (below 0).
=4 - 7
=4 - 4 - 3
= 0 - 3
= -3
3 - 7 = WHAT??? 29???!?!? ITS NEGATIVE FOUR
Integers
What is this application that you are drawing on? I could use some stuff like that.
theres smoothdraw3 which is what khan academy uses but idk about him
you are really a problem solver.
Thank you 🤯🤯🤯
what about y6 divide y3?
= y3
y3
I have a test on this in 3 hours
Your awesome really helped me out I have a quiz today and this morning I was craminh
Why are you saying multiply the exponents then adding them.
how from dividing to subtracting 5:50
😭😭😭
I think its because if you were to multiply you do addition and so the same principal applies to division, you subtract
They're similar operations
i can barely hear ur voice but ty since i have an exam coming .
He teaches better than my maths teacher 😂
thanks
When u hear his voice u know that ur saved on your recitation haha
I feel like we just making up rules as we go
4:14 this is my problem
8:24 just for me :)
Thanks
Maybe I won't fail my test -3-
i failed 2 in a row lol
Same

b 2 . b
your udemy account doesn't work.
2:04 how did you get eight
It's 8 because 2^3 is 8.
2x2x2 = 8 Numbnuts
when there is a small number above a number, that's an exponent. it inticates how much times the number multiplies my itself
on a keyboard it is represented as 2^X
for example 2^3 would be 2x2x2
and 2^5 would be 2x2x2x2x2
2:01 it’s not 6?????
2^3
= 2 x 2 x 2
= 4 x 2
= 8
2x2= 4x2= 8, have you never learned exponents in 3rd grade?
Owen Zausch no or at least not that I remember
@@owenzausch7391 its not 3rd grade. for me atleast. i learned in like 6 or 7
@@benji4226 Am I the only who learnt them in 1st grade??
I need more help 😢
Thanks but u lost me at 10min +
Ally WhatsGaming that's because he stopped teachimg!
Ik is not math related and ik what im about to say is stupid but you sound like lil tecca😂
Good lesson but u went way to fast!
dumb ass
Kobe Number2 no he didn’t, I sped it up in fact
im wathching it on 1.75x speed lool and its still slow
i didnt understand anything lol xx

Ashley Campbell are you 6 or something ffs
Ashley Campbell oh wait you won’t know what “ ffs “ means
what the actual fuck is wrong with you i hope your in highschool suffering on algebra because you didn't watch this
lol stupid, ignorant, no-brain
BOOOOOOOOOOOOOOOO!
LOL!
We r not potatoes quit talkin to us like we r
Then u should prob stop callin him a nerd u potato
