1 For example, range of 6 bit 2's complement form binary number is from (2⁵) to (2⁵-1) which is equal from minimum value -32 to maximum value +31
2 The range of Sign-Magnitude form is from (2^(n-1)-1) to (2^(n-1)-1). For example, range of 6 bit Sign-Magnitude form binary number is from (2⁵-1) to (2⁵-1) which is equal from minimum value -31 to maximum value +31
3 Multiprogramming means that several programs (sequences of z/Architecture® instructions) in different stages of execution are coordinated to run on a single I-stream engine (CPU). Multiprocessing is the coordination of the simultaneous execution of several programs running on multiple I-stream engines (CPUs).
Multiprocessing is a system that has two or more than one processors. In this, CPUs are added for increasing computing speed of the system. Because of Multiprocessing, there are many processes that are executed simultaneously.
Difference between Multiprocessing and Multiprogramming :

S.No.	Multiprocessing	Multiprogramming
1.	The availability of more than one processor per system, that can execute several set of instructions in parallel is known as multiprocessing.	The concurrent application of more than one program in the main memory is known as multiprogramming.
2.	The number of CPU is more than one.	The number of CPU is one.
3.	It takes less time for job processing.	It takes more time to process the jobs.
4.	In this, more than one process can be executed at a time.	In this, one process can be executed at a time.
5.	It is economical.	It is economical.
6.	The number of users is can be one or more than one.	The number of users is one at a time.
7.	Throughput is maximum.	Throughput is less.
8.	Its efficiency is maximum.	Its efficiency is Less.

4 Multiprogramming is a method of running multiple programs over a single processor by sharing the processor time in the time sharing environment. While multithreading is the process of running multiple threads to execute concurrently, supported by operating system.
Multiprogramming – A computer running more than one program at a time (like running Excel and Firefox simultaneously). Multiprocessing – A computer using more than one CPU at a time. Multitasking – Tasks sharing a common resource (like 1 CPU). Multithreading is an extension of multitasking.
5 Using identities: yz + xyz' + x'y'z = (x +x')yz + xyz' + x'y'z = xyz + x'yz + xyz' + x'y'z = (x'y'z + x'yz) + (xyz + xyz') = x'z(y' + y) + xy (z + z') = x'z + xy
