Accessing Numeric pad keys on a tenkeyless keyboard

[gizmo1990]

I've started using a keyboard with no numeric pad to cut down on space. Unfortunately a program I use has a function which is locked to the number pads + and - keys. I thought there would be some kind of way to access these key presses in the form of a key combination or shortcut but I can't find any.

Does anyone know of anyway I can initiate these key presses in Win10 via key presses on my tenkeyless keyboard?

Any advice greatly appreciated

Thanks for the reply. I've checked with the keyboard manufacturer and now luck unfortunately. I have how managed to map the keys I need via autohotkey. It's it's a reasonable fix.
