Write a program for 8085 to multiply two unsigned 8-bit binary numbers using successive addition method. 3. Write a program for 8085 to divide two 8-bit binary numbers. 4. Write a program for 8085 to compute the difference between two 16-bit binary numbers and display the result. 5. Write a program for 8085 to find the sum of a series of N unsigned 8-bit binary numbers and display the result. 6. Write a program to pick out and display the largest of an array of N 8-bit binary numbers. 7. Write a program for 8085 to sort the given numbers in descending order. 8. Write a program to divide the contents of 8900 into two 4-bit section and store the least significant 4-bits as the least significant bits of 8901 and most significant 4bits as the least significant bits of 8902. Multiply the contents of 8901 and 8902 and store the result in 8903. 9. Write a program for 8085 to subtract two BCD numbers. 10. Write a program for 8085 to add two multibyte BCD data. 11.
