CS 473 - Base Conversion Review

I want to give you a chance to brush up on your base-conversion and non-decimal manipulation skills, but this is really stuff from prior classes so there isn't much point in demanding it as a homework assignment. It's up to you whether you do this; just be able to manipulate the numbers!

  • Binary arithmetic
    The following problems are expressed in eight bit, 2's complement, binary. In the multiplication problem, your answer should be a sixteen bit number. In the division, your answer should have a quotient and a remainder.
    1. 01100101 + 00010011
    2. 01101100 - 01110110
