    The signature of a great teacher is making that which seems difficult easy to understand. That makes maths and numbers fun and enjoyable, confidence builders. Good show thanks.

    Nice video to remember what I learnt like 25-30 years ago and probably forgot 15+ years ago. I often wish there was a quick way to recall all the math I used to know. Only remember the very basic stuff. Not that this is anything advanced either. But I basically just remember how to add, subtract, multiply and divide. And some simple trigonometry, sad.

      BAH! It was fun when ja was in high school and college. Im back in college for power engineering 3rd class. Alrdy got my 4th class. AND ITS ALL F#%*in math. We did complex quad equations in the first exam with FRACTIONS. I HATE FRACTIONS! Lol. I love math but we moved so fast and had no
      Info :(. Or less. It was also a mix of calculus but at a much extreme level

    This method was really helpful! Should aid me in my exam. In a recent video, you said we can ask you to say anything in your 'nassaly thor voice' so can you say, 'Koala's should reign supreme on earth from ChattierTooth.' Asking for a friend.

    Sir I have a doubt
    In one of ur previous video u discussed a beautiful method of multiplication using Vedic maths
    But sir how to solve it if we get 2 digit number as carry as in the case of multiplication of ( 69 × 96 )

      eventually imaginary numbers must be used - (yes, there are imaginary numbers in mathematics)

    So, in the last problem where the result is 4+-√11, I got on calculator that;
    4+√11=7,31(appr.)
    4-√11=0,8 (appr)
    Before that I got my results for plus=7,13 and for minus=0,6.
    I think I wasn't that far though. I approximated some of the things I calculated too. Good for me since I didn't start doing quadratic formulas in school yet.

    3x^(2) - 10x - 8 = 0
    x = (10 + sqrt (196)) ÷ 6
    x = 24 ÷ 6
    x = 4

      X=4
      3(16)-40-8=0
      48-40-8=0
      3X^2--10X--8==0
      3X^2----5X--4==0
      3X=8+4=12/3=4
      X=4
