you and khan academy have singlehandedly saved us all

[nicolenoelle]

This video you made cured the tears I have shed due to not understanding each step! Thank you SO much for such a clear, step-by-step, presentation.

[reemmohamed]

A very helpful channel . I appreciate your effort. keep going 💪

[sumangkalamveerasami]

Thank you so much for your knowledge its really helpful

[some]

I passed my math final with your channel. Thanks bro XD💕

[kanechabot]

Now do this without a calculator, multiple times, in under 2 minutes per problem Mwahaha! ...welcome to Missouri S&T

[breeb]

helped me so much, it was so easy after watching this video. Thank you !!

[Jowonne]

Thank you for always saving my ass when it comes to science and math

[justengineer]

Helpful, but still need some explanations on the nontabulated interests if One has advance payment 0f say $1220 recovery= $152.5 at 4.5% quarter yearly interest and 8.25 yearly payments? P=1003, how is this result calculated?

How can you tell whether a question is talking about compound interest or simple interest? Got any tips/tricks/secret behind it pls Sir?

[MrEJYourSolarExpert]

love your channel... thank you very much. i have a question... what formula can i use to know the price increase on electric bills? example utility bills have an increase of 4% on average annually. So if a home owner is paying .13 cents per kwh and consumes 2500kwh per year... what would the price per kwh be in 25 years from now? thanks !!!!

[geewizrsx]

What about yearly instead of quarterly or monthly? What wiuld the n be for that?

[hvacwiz]

thanks i knew the formula forgot how to do math lol

[facohido]

so like don't mind but like you do all kind of math like algebra, indices and like ratios so like don't you ever forget them after a while . for e. g I give you a paper right now with all the questions of maths problems that you made videos own . so will you able to answer those or not ?

[solonpeter]

Please can you help me by solve the problem with out a calculator, ,

[dylanbushmire]

What would I put down if it said the interest was compounded continuously

[lowersaxon]

True.But you didn‘t touch continuous compounding unlike in your video 3 years ago. You could have derived „e“ ( Euler‘s number) by the compound interest formula as you of course perfectly know. And I think I‘m not quite conform with the vid from 3 years ago. If A = P ( 1+r)^rt and A =Pe^Rt then with b = 1+r the term e^R has to be equal to b. I don‘t think that r and R will coincide exactly. Suppose b = 1.10 then e^0.0953= 1.100xyz ~ b. So R= .0953 = ln 1.1 and not r= .1. This is not to blame you, on the contrary I think you‘re really great in natural sciences and that many people enjoy your absolutely charming voice and style of educating this stuff. Keep on!
