    It’s all about the base 🎵

    Can you start a new series about competiton math? Like AMC, math league, MAO, etc.?

      Tuanicular I second this. BPRP’s teaching style really suits explanations for competition math. Having an entire series from him on it would be amazing.

    Great reaction to the symmetry! Love the videos.

    I find it easiest to convert to octal first -- dividing by 8 is easily done even mentally (an advantage over hex) and it's 3 times fewer steps than dividing repeatedly by 2. Converting from octal to binary is also easily done, replacing each octal digit with 3 binary ones.

      I read your mind! lol

      you can actually just convert each number in octal to binary then convert the binary to hexadecimal
      example:
      7513=
      (111)(101)(001)(011)=
      (1111)(0100)(1011)=
      F4B
      maybe bprp should do a video on why this works! :D

    I learned a faster method to convert base 10 numbers into binary numbers at a school overseas. Using the remainder logic, first convert the number into an octary form and utilize a remainder table to convert octary to binary.
    1=001
    2=010
    3=011
    4=100
    5=101
    6=110
    7=111
    I don't remember exactly how it's done but it was super fast for converting large numbers.

    I imagine it doesn't work upwards? or is there a slightly different method for up-basing?

    What method can be used to convert a base 2 number to a base 3 number (without having to use base 10)?

      Excellent question. I will make a video on it when I have time. Prob. this coming weekend or so.

    What about negative numbers and fractional part
    for negatives bit negation (base - digit)
    for fractional part multiply by the base and take integer part

      blackpenredpen No.. but from previous experiences it does take about 1 month to send something from other countries to my city, so I think it's normal.
