      4 # Conversion between bases
      5 ## If one radix is power of other radix
      6 Start right, take groups of size *ratio of powers* (e.g. hex to octal — 16 (2⁴) to 8 (2³) — 4 to 3 —convert to binary, group by 3s)
      7 
      8 Ex:
      9 
     10 | Binary (2¹) | grouping (1/3) | Octal (2³) |
     11 | --- | --- | --- |
     12 | 10100101001 | 010 100 101 001 | 2 4 5 1 |
     13 
     14 ## If not:
     15 - Binary to decimal — multiply & add up powers of 2
     16 - Decimal to binary — identify powers of 2 OR repeatedly divide by 2
