Well, you have described where the wires go - at the other end they will need to go to your cooker control unit. The important thing to realise is that large currents flow in a cooker circuit, and the cable used, and the breaker that protects it will need to be sized accordingly. There really should have been instructions supplied - what do the shop say?
The terminals may be the type where the wire wraps around the threaded post, and is then trapped between washers by tightening the nut or bolt. Before using this type of conection it is important to make sure it is mechanically sound, and that there is good metal to metal contact (not just riding on a few high spots) There are various ways of forming the 'eye' on the cable, but the key is mechanical security, and not leaving enough tail that any amount of rotation or shaking loose could cause a short circuit.
For 7 strand cable, a 6-6 split with the 7th strand used to wrap the joint is the 'old way' the modern way is probably compression crimps, but note that these only work in fittings with enough clearance.
The skills required are similar to those used to splice wire rope, and are falling out of favour in preference to crimps.
