    Cells hold a literal or the sum of two other cells. Evaluate them, refuse to loop on cycles, propagate updates, then cache values and invalidate only what an edit actually affects.

    The five steps
    1. Literals and formulas 9 min
    2. Missing cells and cycles 10 min
    3. Updates propagate 7 min
    4. Cache, and invalidate precisely 13 min
    5. Inspect the graph 9 min
