18. Binary Arithmetic Addition 0+1=1 1+1=10 1+0=1 0+0=1

19. Binary Subtraction using Twos complement method

20. Hexadecimal Nuber System 1. Consists of 16 symbols 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F 2. Base of Numbering system is 16. 3. for example 22H,11H,A3H

21. 1. (255)D convert into hex 2 (100)D convert into hex

22. Coversion of Binary numbers to Hex

23. Coversion of Hexadecimal numbers to Binary

24. Task 1. D2H=?2 2. 45h=?2 3. (11001001)2=?H 4. (1111 1111)2=?H
