Do you have a PC or laptop? = I have a PC.
Operating system: Windows 10.
If you have a PC, you should also have a standard keyboard and it has a numpad - on the far right the area with the numbers.
Unfortunately my keyboard has no numpad on the right. There are keyboards that have numpad and there are keyboards that don't have numpad.
Then you were unlucky. Why do you buy something like that? Not enough space on the table?
I had enough space. My table is very big. I don't think the decision was smart. I bought the keyboard because I thought what I needed the numpad function for, but I was wrong.
There are num pads (number pad) that can be connected via USB. E.g. At Amazon with cable or wireless
