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.
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.
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.
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!
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)
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

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
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 👍👍
You saved my life . Thank you so much for your help 💗

My Algebra teacher is out getting knee surgery and the sub is clueless, so this helped me a lot.
im an absolute academic weapon because of u 💯💯
Man i had and important quiz yesterday i got the results and i aced it thank you so much you are the best
Thanks sir u really helped me,I have an exam coming up
I fuckin love this guy always comes in clutch wit last minute studying for a test
Godbless , i really like it , 😊, your video help me to understand what math is
This guy is a legend why isn't he verified?
Test about this is tommorow. Wish me luck! 🤞
you are really a problem solver.
When the next thing you're learning in class is right here. Stay ahead of the game people.
I really find this helpful thank you
Thx that rlly helped me 👍🏼
I really like this video
Thank you 🤯🤯🤯
Very helpful
Tnx I learned from you
very helpful
this was soo useful thanks
I turned this on to help me sketch-
Your awesome really helped me out I have a quiz today and this morning I was craminh
He teaches better than my maths teacher 😂
When u hear his voice u know that ur saved on your recitation haha
That website is good for asvab test on mathematical and arithmetic??? The one you just showed on the vid
Great lesson! Quick question though, why'd you remove the variables at around 6:44?

Can I ask? What if the equation is (0.15t)(-0.2d), what would be the answer? Its kinda confusing for me.
It's been 2 years. You have the answer now?
What about 8² / 8⁴?
Can you guys help me?

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...
Gaming - ActualBad 1/8^2
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
Because when you subtract the minuend that is lower than the subtrahend, you would get the negative answer
i can barely hear ur voice but ty since i have an exam coming .
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)
Thanks
I have a test on this in 3 hours
what about y6 divide y3?
= y3
y3

In the multiplying part, he says multiply the exponents but then he adds them so I’m confused
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
4:14 this is my problem
8:24 just for me :)
how you put it negative ?????
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 feel like we just making up rules as we go
Why are you saying multiply the exponents then adding them.
❤❤
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??
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
Maybe I won't fail my test -3-
i failed 2 in a row lol
