Comparing NumericFields and Hidden Text

I think the below questions should be easy to do but my brain and google have not been my friend. So I would live the experts to help

I have 2 NumericFields (1 & 2). If 1 is greater than 2 i would like hidden text1 to be visible otherwise stay hidden.

Also would like a 3rd numericfield to show the sum of NumericField1 - NumericField2.

I have tried quite a number of different things in script editor but nothing has worked.

Thanks in advance
