If you have completed the core seminar and want to apply quintrays, you can find help here for equal-distant calculations, center of symmetry, reverse direction, composition conversions, analytical conversions, and calculation of dual apps (reverse, twin). Enter the data into the cells on the left, then see the solutions after you calculate them yourself.
Do not interfere with the cells that calculate the solutions! Enter the values in the cells with the dash –.
To use the calculation tools, follow the steps below, depending on whether you have a Google (Gmail) account or not:
Case A: You have a Google account (Recommended)
Click the button you are interested in.
A Google page will appear asking: "Do you want to create a copy of the document?"
Click the "Create a copy" button.
The file will open immediately and be saved to your Google Drive. You can now enter your values in the Start and End cells and see the results.
Tip: If you accidentally delete a formula and the calculations stop working, don't worry. Just create a new copy of the file from the original link on this page.
Case B: You do NOT have a Google account
Open the file you are interested in in a new window.
In the menu at the top left, click File > Download.
Select Microsoft Excel (.xlsx).
Save the file to your computer, then open it in Excel. (It is possible that some functions will not work correctly.)
