2. INTRODUCTION
In today's generation, people are surrounded by technology. Technology
is ubiquitous and we can see it everywhere. We use it in our everyday lives for
communication, transportation and in getting information. We also use
technology to make difficult tasks simpler. Specifically we use programming in
solving problems encountered by the people. We find ways so that we could
experience convenience and we can easily go on with our lives.
In order to apply the lessons we have learned in our subject Information
and Communication Technology 10, we students of 10-Einstein are required to
make our own program that could help us in our studies. We need to make
calculators involving our three subjects namely Math, Science and Health and
incorporate what we learned in the MDAS activity in Visual Basic. We thought of
computations and problems needed in our subjects. We chose the problems
that will use the help of calculator and will involve very large numbers. Inputting
very large numbers in the calculator can be confusing so we found a way to
make things easier. This can help students in their subjects especially in the
incoming quarters.
These programs wouldn’t only be beneficial to our fellow students but also
to the people around us. We made a program that could compute for the
average water requirement a person should intake in a day. This could be of
great help to reduce the case of dehydration especially on dry season. This
computes also for the conversion of ounce, millilitres and glass. We also made
the Base-Percentage-Rate conversion so it would be easier for students to
understand the concept of getting the n% of a number and then getting the
percentage of a percent. Lastly, we also made a program that could compute
for the number of moles and molar mass, a project dedicated to chemistry
students and enthusiasts who would like to further understand the lesson of
molar mass and moles.
As we study more about the other features of Visual Basic, surely it
wouldn’t be impossible anymore for us to make complicated calculators and
formula machines. If we could make this happen we wouldn’t be far from the
super-modernistic future we imagine. But behind all this, let’s not forget to look
back and be grateful to the people who contributed their gifts of talents for the
better of the people today.

3. PROCESS
PLANNING
We made plans in our program and all of the plans are based on our
lessons in the past years. We chose topics from these, analyzed the flow of the
program and visualize the kind of programs we will make. We thought of harder
topics and tried to make it simpler for a user. Instead of the user doing it
manually in just a simple calculator and always saving the answer, we made a
more convenient way of doing things and had the formulas set in our code so
that in one click, the user can get the information he needs. For our science. We
planned to do about the computation of number of moles and molar masses,
which is obviously part of chemistry. For Math, we planned to do the process of
percentage, base and rate that could help in investments. Lastly, for Health, we
planned to compute the average amount of water a person has to drink in a
day with three different unit of measurement for volume so that they could
easily measure the volume of water depending on the unit they use mostly.
CREATING THE GRAPHICAL INTERFACE
In creating the graphical interface, we tried it also in a way that the user
can operate the program easily and he will not get confused. We also put some
pictures and color schemes to add to the aesthetics. In each program there is
just one button and hopefully that one button can show all the outputs or results
already. We thought of how the user can best manipulate the system of the
program. We tried using a colourful scheme so that whenever the user uses the
programs he/she wouldn’t get bored easily and will really try out the program.
Since the graphical interface has also great influence on user’s enthusiasm to
use the program we made sure that it would get the attention of the user and
would really be a satisfactory to the eye of the user.
For us, it is easier if you work on the design and layout last so you would
have enough time to think of what color combinations you would like to use for
your program.
CODING AND TESTING
In coding, we already knew how we could do the algorithm without really
much help and problem. We just based the codes based on our MDAS activity
where we used a combination of the four operations. We also added other
things we learned in our first quarter and somehow incorporate it with our

4. output. It is also important that the programs run and there should be no
problems that will be encountered by the users.
Since we’re just basing it from a past lesson we could follow the pattern
and try experimenting the pattern that we already have. We could add more
operations and try combining different concepts with each other. Even though
we had a lot of trials in running the project that’s fine because we were able to
make smoothly running programs. We made sure that there would be no error
anymore on the command, operation and the control.
MAINTENANCE
The programs we made could still be modified and improved. For the
water requirement we recommend using a combo list on the weight part and
try taking in pounds as one of the choices there. Also try adding more
conversion factors like pint, quart, tablespoon etc.
BENEFITS
1. The students. The students can readily use the programs that we made if they
have assignments especially in our Science program. Or they can just use this to
check their answers after answering their problem sets in chemistry. Students
who will be using our program in math could also understand their lesson better
by using out calculator as basis for their answers while computing.
2. The other users. Besides students, other people could also use these programs.
In our Math program, normal people could use our calculator to find
percentage, base and rate. It could be used by executives or small store owners
and business involves lot of numbers with the percent sign always. Another is the
program in Health. Water belonging to the category of food is one of the basic
needs of people. People need to know if they still maintain the appropriate
amount of water in their body. The correct measurement of amount in liters can
be converted into number of glasses and it would be easier for a person to
monitor the amount of water he should be drinking.
3. Maker and programmer. We, as the programmers also benefitted because
we were able to apply what we learned from those three subjects and
especially what we understood in ICT. It shows that when someone is learning, it
could be a source of a new idea or a new thought which would lead to more
beneficial and useful innovations in the future.
