Can you suggest me how to enable calculation values in a field

When we use short answer with the help of using input mask can you suggest me how can we enable calculation vaules in it.

May I suggest you can either use a different field for calculations that allows adding calculation values or you can add a calculation widget to your form and then make the calculations with that.

If you'd like you can share the URL with us and let us know what you'd like to achieve so we can certainly have a look and help you with your workflow.

Thank you!
