This work was centered on the Design and implementation of a
simple scientific calculator for education organization. The study traced
calculator system as a tool to completely change mathematical knowledge and
sophisticated problems solving strategies had advanced the field of simulated
engine in mathematic.
This project work also focused principally on numbers and
arithmetic operation. This researcher investigated the manual system in detail
with a view to finding out the need to automate the system.
Interestingly, the end result of simple calculator system was its
ability to process number and operators, and provides a useful result.
Therefore, this project will help immensely in the following way.
Easy calculating of tedious mathematical problems, easy to retrieval of errors
and it will also be of a good assistance to any researcher on these topics.

CONCLUSION AND RECOMMENDATION
Ever since, tedious
mathematical problems in the organization is not a simple one, that is to say,
the process can be said to involve a lot of procedures or protocols which
ranges from insertion of figures for tedious calculation, processing of numbers
and retrieval of errors. However, because of this, there is the need to
accomplish an extensive research to discover the intricacies involved in the
entire process. So the researcher decided to embark on this work design and
implementation of a simple scientific calculator.
Computer have gone from being fantasies of science, fiction of realities of
everyday life, especially in the offices, school (educational organization).
This work is a research aimed at solving the above promblem. When this system
actualizes, it would be received of solving tedious calculations and
sophisticated mathematical problems.
STATEMENT OF THE PROBLEM
In computation of numbers,
there ties several kinds of problems in solving tedious arthimetic operation
with simple calculator. Having been facing a lot of general problems, the
problem identified below relate to computation of numbers:-
low and slow speed of the calculator
Inappropriate representation of data
Loss of figure in computation of higher numbers
Inability of handling complex arithmetic operation
The processing of numbers are in binary coded decimal(BCD)
To check these problems in
computation of numbers solution such as
Introducing a standard scientific modules into the entire system
to perform tedious arithmetic operation.
Apply logic and algorithms simulation to the system
Introducing scientific calculator that will operate in the correct order rather
than four function calculators
Checking overhauling of the system that are deemed incompetent
PURPOSE OF THE STUDY
Since it is time saying that
there is no smoke without fire ,the effort to carry out the research was not
first conceived. To particularilize the matter and concept ‘what a
calculator can do in solving tedious problems and how it is done? There is
serious need for this study.
In view of the aforementioned problems inherent in the design of the simple
scientific calculator, the purpose of the study is to provide on overview of
the simple design calculator.
Another purpose is to change the processing number from binary coded decimal
(BCD) to ASCLL coded which is better and familiar with today computer
processing. The format 12H2- cannot be used in the design again, this means
that it will not be controlled by a hardware state machine.
Finally, the purpose of this work is to improve the speed of the simple calculator
in such a way that it will maximize the hardware needed and reduce the cost and
complexity of the machine. This will help us to enjoy the anticipated high
speed of our calculator.
AIMS AND OBJECTIVES
This product will be tested
based on the following objectives:-
To examine the current procedures employed in computer with regard to the
To improve the speed of then simple calculator in such a way that it will
reduce complexity in solving with simple calculator.
To design a simple calculator that ensure timely processing
To design a calculator that will change the processing number to ASCLL code.
And finally, to reduce the problems immensely and provides a release working
SCOPE OF THE STUDY
The process covers only of two
approaches used in producing the simple calculator which are logic simulation and
algorithm simulation due to the fact that it is difficult to develop a
scientific simple calculator that will calculate every existing calculation in
all field of study, this research has been limited to arithmetic operation
The study also involves the visual basic programminjg language for the writing
and running of the source code or program. The brief description on processed
data in equally included.
The project will be designed
and implemented based on the following assumption.
That the use visual basic programming language will make the program to run on
That the project will ensure timely and accurate processing in computer.
That the speed of the computer will improve after the implementation of
the anticipated simple scientific calculator.
Finally, having done this that
the facts and figures manipulated are reliable, the designed software to run
