> as long as you add the bits from least significant to most Thanks, although I already understood what you explained, this bit made me realize more clearly the detail I was tripping up on. I was never imagining the 1-bit adder to start anywhere _but_ the LSB, what I couldn't figure out was why it couldn't simply iterate the bits in reverse logical order for big endian... I'm guessing there is a good reason why serial processors can't read a sequence of bits in reverse logical order, and it probably applies to modern CPUs too? either that or it's a design choice that cannot be dynamic. I should probably pick a book up at this point, thanks for answering my questions.
