Thank you. You helped me more than my teacher
Glad my video helped you with compound interest Alfredo!
Mario's Math Tutoring I was wondering what you plugged into the calculator ?
You can either do it in steps by following the order of operations PEMDAS or you can use lots of parenthesis and put it in all at once.
Hello I'm a student From Malaysia... I need some help. Can i get your contact. Thank you

Preach lol
Aame i was abt to cry😂

Holy cow dude in less than two minutes you've taught me how to do my math homework and I don't have to take notes on a 30 minute video, thank you!
Glad I could help!
Actually an amazing simple man, the world needs more people like him
sorry, how do u compute for the last equation 5000(1.02) to the 8th power??
Use bedmath
Beautiful :D I needed a refresher. Thanks, dear teacher!
You’re welcome Alejandro! Glad my video helped you!
Teacher uhhhh
After looking at multiple examples and the textbook provided by school, this video is the only thing that helped me understand what to do-thank you!
You’re welcome Ann!
Thank you all the teams rely i got the exact and clear understanding from your stereotype lessons.
Glad you liked the video!
I love you man your voice is so soothing
Explained very simply. Thanks :-)
You’re welcome!
Can’t it also be
A equals p(1 plus r) to the power of n?
This was so helpful! My textbook said to do the regular interest formula the same number of times you compound. That was cool until one of the problems was biannual compounding for 22 years....
very well explained! thank you!!
You’re welcome Parker! Glad you liked the video!
I have a question: what do you do in the last step with the calculator? Do you multiply?divides? I can’t seem to figure it out.
Use bedmath
Awesome Tutorial!! Love your teaching style! Keep up the awesome work!! Cheers & Happy Holidays! 💫🎄
See teachers it's not that hard to be able to condense a complex and difficult thing to understand into a short 2 minute lecture. And if you had taught me this in math class I wouldn't be having troubles with my finances now.
I wish you were my teacher sir thank you.
Thank you it's now easy to me
Thank you so much Dude I have one day till the end of the semester and this helped a lot
Glad my compound interest video helped you Isiah!
I have a query, isn't 8% 0.08 and 80% 0.8?
Yes
@@MariosMathTutoring looked like you said 0.8 for 8%il instead of 0.08
@@takundamhete7476 he literally wrote down .08 which is the same as 0.08
quick question - i have a final exam tommorow how did you get the 4 x 2? Please respond quickly
thanks
Thanks for the video. What if you add the interest compounded to the principal every time? What's the formula for that?
That’s what this formula does.
Explained it quickly and it was easy to understand 😊
It's really useful for me so thank you so much
Thanks, Explanation was clear to understand
You’re welcome Mukesh! Glad you liked my explanation!
Super video! I applauded for £50.00 👏👏👏
how did u get the raise to the power of 4.2?
Thanks for helping me brush off the cobwebs. I had no idea back in middle school that, I would eventually use these formulas.
Happy to help!
explained so simple. thank you!
Glad it helped!
Thanks , great explanation
you're*
Can you make a video of that example without using calculator please. Thank you!
Sir wonderful teaching
Thank you explanation was clear 😊
Glad you liked the video!
thank u sir that was explained very nicely
Thanks this helped a lot
You’re welcome Lanie!
Does that mean the total amount earned is directly proportional to how often in a year the amount is compounded
very well explained. Thanks sir
You’re welcome!
How do u do yearly
so quarterly means they are paying this interest every quarter right,,,but simply putting 4 sounds wrong ,i thought it should be .25 or 365/4=91.25 but since t=2 then maybe that is why you used 4? idk but i know if its calculated daily then daily then n=366 and t=1?
Can you please tell me what the 1 in the compound formula means? 100% of the original amount deposited??
9 months late, but the 1 means that you're adding onto what you deposited. If you multipled 100, by say, 5%, 0.05, youd get, 5 dollars. If you multiply by 1.05, youd get 105, so youre gaining money not losing any
Hello this is my first time learning this so I'm ready to learn sir 😊
Very helpful💕💕
You just saved a 7th grader, thank you so much
you just saved my maths assignment👍
Thank you sir for simple and clear explanation
Thank you so much , Sir. 😄
You’re welcome!
My exam is so near. Watching this help me to recall the concept
All under two mins, stupendous. Next time show the final math for the icing on the cake, some folks don't know order.
tysm it helped me out
does anybody know how much will be the N if the investment is 6 months on the acc? The account pays 5% monthly, however, is for 6 months, do you multiply 12x2 or 12/2?
12/6 so it will be 6
Aww I’m so stupid I can’t understand anything, can you please explain. Thanks for your effort though!!
This is the only video that helped me understand 😭 THANK YOU
Glad it helped!
If my answer is in decimal can I round up if necessary ?
Very rad, thank you
Glad you liked the video!
What would u divide it by if it’s not quarterly but annually ?
Annually is n=1
I love you mario
Fabulous elucidation
?
Thankyou sir , you clear my all confusion 😊
Most welcome 😊
You saved my grade just now.
Nice ...make some trick for competition
thank you, that one statement about finding the % per quarter and multiplying that by the number of quarters cleared everything up
Awesome! Glad it helped!
thank you very much
You are welcome
Thank
Thanks my math teacher just throws us a packet and says nothing snd i have a test tomorrow. I just learned thanks to u so thanks 👍🏼

THANK YOU OH MY GOD I WAS LITERALLY SOO CONFUSED 😭😭
You’re welcome!
Bro was sent by heaven
i have to do this in 6th grade, great
Sir i am a big fan and your subscriber.What does the 4.2 means on the top is it yeara or quaters i like your videos allah bless you ameen
I'm here to properly prepare for a unit test
whats the value for annually? i know quarterly is 4. good video
Annually n=1
Thanks
You’re welcome Fahim!
So do i just ignore the 1?
Could you answer this 1500 is borrowed at 10% p.a how much is replayed after 2 years
how lazy are you lmao
Thankyou sir love from india
How did you calculate the 5000(1.02)⁸
Do the ( ) first so 1.02 to the 8th power is 1.17166 then times that by 5000.
Ahhh I c thanks this helped
Here's a sub
*edit: Just figured it out but realised I need to study and learn maths syntax. Great video btw, thanks.
I'm lost. I didn't get the answer I think because of not understanding brackets. I did 5000 x 1.02 x 8 = 40,800. I know two letters next to each other are mutlipled like nt. Can someone explain were I went wrong?
Ah I think I see amount starting at 1.02 repeated 8 times.
1st round = 5100
2nd round = 5202
3rd round = 5306.04
4th round = 5412.16
5th round = 5520.40
6th round = 5630.81
7th round = 5743.42
8th round = 5858.29
So P is the start amount and brackets is applied to P then P becomes the result of that and this is cycled 8 times. You could say what is in the brackets is reflective.
8 times {P = P * 1.02}
@@supermoon4861thanks for the explanation, I was confused on that part as well
Plea show as when you calculat
thanks professor xavier
how did you get the 5858.30?
True i can't understand how did he get the 5858.30
Do I have to learn this-
man.....high school sucks-
I’m doing this in grade 8! Your just learning this in High school?!
@@shayelymb6838 I am in grade 8 where I’m from 8th grade is on high school high school starts at 7th grade and ends at 11th grade
The teacher did tell us we’d be needing this is further grades as well though-
I love you

Glad you like my videos!
this was so useful to solve my python homework. You are a great teacher man.
Glad you like my videos Fabricio!
is that the guy beluga uses his videos as if he’s Walt?
How about Biannually?
Twice a year ... n=2
me watching this before my exam, streesed
What would be my n if my question says continuously not quarterly?
You would want to use a different formula than this one...I explain how here: Compounding Continuously Pert Formula ua-cam.com/video/dFsBfi9W7sQ/v-deo.html
Tomorrow I have a final exam. Thank you for teaching me.
You’re welcome! Good luck on your exam! Report back if you want and let us all know how you did.

I wish you did it without calculator but thank you
I'm not in class anymore for obvious reasons so I couldn't reach out to my teacher to help me with this, thanks for the short and simple video.
You’re welcome Vincenzo!
'r' IS THE INTEREST RATE PER YEAR/ANNUM.
So bad at learning things😢 I'm such a slow learner, i didn't get it ill watch this many times just so i could understand the topic
That was amazing! I understood everything you explained in the video! It was just all crystal clear! Thank you for making this video! By the way, I subscribed.
