Nothing you change here touches the recordThis is the whole calculation, drawn out. Boxes on the left are figures you typed in; boxes on the right are the answers. Every arrow shows a number moving from one place to another. Click any box to see the sum written out with your own figures in it, or drag a slider on the right and watch the change ripple through. Nothing here alters the record — it is a sandbox for asking “what if”.
