 Basically, I have added an explanation for my own application. It's the expense management for basic bachelor's. Most of the people are here who are moving some money to someone else. I'm sure of that. And once they're moving the increases of two months, let's say two months, the expense can't be much more complex. It's very time-consuming concept. So let's say you might not be familiar with this whole process. So I developed a small application. It's like a simple log-in script, like your first name. You can log in to this application. I distributed this whole experience as per the outings, like these events. We sometimes go shopping, we sometimes go for food. We shop again to get some groceries at home. So this is like an outing for us. So I have classified this whole as an expense thing in kind of an outings. I have created an example. I was not able to complete this application completely. This is how the expense program may appear. This is the important thing. The users involved in this meet-up. Let's say these are the poor people. And we need to determine how much people have invested their money. Like expended in this, above the house. So just click on this, you will see nothing. It is supposed to show expense done by function every person in this above house. You can add yourself. You can add three more people if you want to. Let's say I have added three people. You just submit it and your outing is created. Then the expense gets automatically categorized as per the outing. So at the end of, find your own expense. Like how much expense you have done by yourself. Then you can find your own expense. Like you have done an expense recently. Just like this outing. There is one form for this outing. You just enter the amount. You will be tagged as a payer. And the amount you send to this outing is automatically split up as per the people. This is the user's list for the agent and the outing. How much people have done, which kind of people have done. This is the category. This is the most important part which I have covered. But I have covered the packet part of it. So in this category, I am getting a final digit number. Let's say person one goes to person two. There is one number for that. Total amount. Then person two is owing to person one. Certain amount. Let's say this second amount is larger than the first amount. In what happens? The person two is supposed to get money from the person. Or the exactly vice person. So this is the thing. This I will be typing in this package. And finally you will get a magic number. Like how much money this person is owing to this person. So this is the part I will be typing in the packet. I will be typing in the packet. Sorry for that.
