Hi Zbigniew,
Thanks for contacting Syncfusion,
Query: How to get Numeric keyboard with + - * / as first?
In Xamarin Forms we cannot set required Numeric keyboard with + - */ symbols. However, we can able to set a similar keyboard in the renderer of the Android Native platform by setting the InputType as ClassPhone. We have prepared a sample for your reference and please get it from the attachments.
The other way is to create a new custom keyboard for your control. Below is the link and already we have not tried this. If you want please refer and try it.

Please let us know if you need any other details.
