    So is Reduced Instruction Set like in the old assembly days where you couldn’t do multiplication, as there wasn’t a command for it, so you had to do multiple loops of addition?

      Right concept, except you’re off in scale. A MULT instruction would exist in both RISC and CISC processors.

      The big difference is that CISC tries to provide instructions to perform much more sophisticated subroutines. This video is a fun look at some of the most absurd ones, to give you an idea.

      Nah, the Complex instructions are ridiculously complex and the Reduced ones can still do a lot of stuff.
