Hi thanks for the module

It is working as expected, but I was wondering how I could rewrite mathematical expressions into more human sentences but maintain the numerical values.

For example, when dealing with stock management a simple views table may show like

Goods +10
Goods -5
Sum =5

I would rather it be shown as
Goods in 10
Goods out 5
Total = 5

So the basic principle is a positive number would have one sentence preceding, and a minus number would have the negative symbol removed and have a different sentence preceding.

Do you know how I could achieve this?

Thanks for any help
