    There are these questions in college entrance exams with like super long years compounded quarterly; boy, it takes a long time. I am here to find a shortcut; it is the same way I try to solve it. I skipped it in the exam.

    Thank you so much

    9:51 how to raise something like that 1over20 on the calculator



  7. Our Package on February 6, 2023 at 2:02 am

    thank u soo much u saved a life from D grade and put an A



  8. TTV_Eruptour on February 6, 2023 at 2:03 am

    Thank you had a quiz the next day and had the formula mixed up.



  9. Istink Aspoopy on February 6, 2023 at 2:04 am

    Isn’t quarterly 3/12,12 ofc being the amount of months in one year. So, when we talk about quarterly, surely we’re talking 1/4 of a year, which is 3 months? I just hate seeing so much comments not pointing this out maybe there are some but, it would be a hell of a scroll lemme tell you that much. Anyways, helpful video really helpful I don’t necessarily think it’s the explanation more of the presentation.



  10. junlit ompad on February 6, 2023 at 2:06 am

    you are sayop bro, instead of .79 its .71 i double checked it with my calcu.

    How about bimonthly



  14. AsimoImposter on February 6, 2023 at 2:10 am

    am i doing something wrong here…when i type in 20000(1.0066667)480 exactly as its stated I am getting a syntax error. Please help.



  15. Christy Toledo on February 6, 2023 at 2:11 am

    @TheOrganicChemistryTutor
    At 4:49/22:05 (timestamp) – Why am I getting $485,475.42 when I calculate 20,000 * 1.0066667 * ^480? Instead of what you got… $485, 467.79?



  16. flame wolf on February 6, 2023 at 2:12 am

    My question to this is do you absolutely have to use logarithmic to solve for compound interest cause at the start of the video he worked a problem out and it didn’t seem as complex and many steps as the logarithmic method



  17. Roszy Peterz on February 6, 2023 at 2:13 am

    Best explanation 😊



  18. Angel AP on February 6, 2023 at 2:13 am

    life saver bro. god bless. keep safe always bro



  21. zenku GAMiNG on February 6, 2023 at 2:17 am

    how did you solve this 20,000 (1.0066667)480



  22. johnpro2 on February 6, 2023 at 2:18 am

    5:30 after 45 years John’s 2 million dollars might buy a small car..perhaps ?(possibly electric). Best John buy some real estate..inflation will make him richer instead of poorer



  23. Kai Jauregui on February 6, 2023 at 2:19 am

    You never show how you got the answer stupid



  24. alana muniz on February 6, 2023 at 2:20 am

  25. kɑɾӀօ on February 6, 2023 at 2:20 am

    4:33 do u just times 20.000 with the 1.0066667 and 480 ?



  26. Milagrosa Raagas on February 6, 2023 at 2:23 am

    4:42 What was his way of computing to get 485,467.79? Because i multiplied 1.0066667 x 480 and got 483.200016, sorry i dont know

    6:58 How did he get the answer of 68.376152? Thank you

  40. AJ Johnson on February 6, 2023 at 2:37 am

    Your vids are very clear but I’m very slow. How exactly is the inverse incorporated into the problem. How would I do the inverse on a calculator. I used e on mine and it did something different. Am I doing the inverse of 2.16?



  41. SnowBunnyHunter on February 6, 2023 at 2:39 am

    He made these functions sound so easy and explained them in such an amazing manner. Thank you so much!



  49. Jash Brown on February 6, 2023 at 2:47 am

    4:41 in my scientific calculator it shows 485,475.427 😅?¿



  50. Zai Xenpai on February 6, 2023 at 2:51 am

    do we need to raise to 480 after multiplying the 20k and 1.0…..67?
