Lesson 5 - Twos complement & Binary Shifts

This educational material introduces two fundamental concepts in computer science: binary shifts and Two’s complement. It explains how binary shifting manipulates binary numbers by moving their bits left or right, effectively performing multiplication or division by powers of two. The document then details Two’s complement, a method for representing both positive and negative integers in binary, highlighting its importance for mathematical operations in computer systems. It provides clear instructions on how to convert denary numbers to their Two’s complement representation and vice-versa, alongside formulas for determining the range of values representable by unsigned and signed integers for a given number of bits.
