Change the "ConnectionString" field's value in the 'backend/appsettings.json' file to your absolute directory location of the database which is 'calculationDB', so that it can locate the calculationDB in the backend directory.

I kept the project in /home/shahir/Projects/Web-Projects/asp_projects/ so the "DefaultConnection" value is set to "Data Source=/home/shahir/Projects/Web-Projects/asp_projects/calculator/backend/calculationDB.db;"

If you keep the project in /home then the string will be "Data Source=/home/calculator/backend/calculationDB.db;"

1. Open one terminal and cd to ./calculator/backend directory
2. run 'dotnet run' to start the backend web api application
3. Open another terminal and cd to ./calculator/frontend/frontend
4. run 'ng serve -o'
