      3 - logs are inverse operations to powers, like roots, except they give us different inputs to the power
      4 - lg means the normal log {log sub 10}
      5 - lb or ld means {log sub 2}
      6 - trunk(lb(x)) + 1 tells me the number of bits needed to store x
      7 - {log sub b} x = {log sub c} x over {log sub c} b, this is very important
