Pick two conventional reduction half-equations. See which one runs as reduction, which one reverses for oxidation and how the overall cell reaction follows.
Choose two different redox couples to start.
Keep the notation conventional
Write each E° value using the reduction couple in the same order as the tabulated half-equation. If the chemical reaction runs backwards, reverse the reaction equation; keep the E° couple in its conventional order.
