Calculated helper


I would like to propose a simple calculated helper.

Where you can simply add, subtract, devide or multiply entities with eachother or by a constant.
for example add 2 or more entities for a total or devide an entity by 60 for min instead of hours.

I know you can do this in a template but wouldn’t it be great to do that in a helper?

Thank you!
Keep up the good work!
