"The problem , as we'll see below, is that when you add to the above framework of particle exchange the quantum requirment that one iclude all the histories by which an interaction can occur - for example, all the ways the force particles can be exchanged- the mathematics becomes complicated."
Asking: I can't understand the italicized part. Is that ' above framework of particle exchange' and ' the quantum requriment' apposition? Or, Does that mean that 'when you add the above framework of particle exchange to the quantum requirment that ~~~?
It's not apposition. It's just a slightly uncommon word order. A more common word order is as follows.
