Again this is very simple , All you need is two expressions in your columns , it is just adding up two column. like you would do in sql server or any other RDBMS.
Add Two Columns to right of your existing columns and right click the data cell go to expression and use the following expressions to get the desired sum values.
total Product A+D
= Fields!ProductA.Value + Fields!ProductD.Value
total Product B+D
= Fields!ProductB.Value + Fields!ProductD.Value
I am only assuming the names of fields here, you will need to use the field name from your dataset. i.e Fields!YourFieldName.Value
