Hello Del Simcox,
Welcome to Microsoft Community.
You are talking about the number Keyboard in the On-Screen keyboard, as shown below:
There is really no corresponding option in the system Settings, because this option is built into the OSK application. You will notice that there is an option called "Options" in the screenshot, click it to open the Options of OSK, please open "Turn on numeric key pad" and click OK to save.
The OSK page will then look like this:
Click the NumLock button below and you will see the numeric keypad.
