I am trying to understand number systems binary and decimal number systems. How can I convert the following numbers using the least amount of digits?
$(47)\text{base}-10$ to signed binary.
$(-27)\text{base}-10$ to signed and binary magnitude
$(213)\text{base}-16$ to a 10 base number
Here are my attemps:
$00101111$
$10011011$ (or 2's complement: $11100101$)
$531$
Am I heading right?
