Formula collection "Formelsammlung database"
To be able to create databank of formulas, like a knowledge database of formulas to each subject and also a “mindmap” where you can combine the formulas to see which are connected with each other.
so when you solve a math problem you can link a already created formula so next time you look at your notes you see what formula was used and if it doesnt exist yet you can add a new formula to the knowledge data base of formulas.
Also same principle with examples of tasks, like i have a theory on a pdf and then i have to solve an example task and when i solved it i can add it to the knowledge database as example so for the next time i have to solve someting similar i can look at the database for the example how i did it
