Show the formula and its inputs together
Select the cell you want to understand and keep the formula bar visible. If possible, arrange the sheet so the referenced cells are also on screen. Include the row and column headings: they give the explanation a stable address instead of an ambiguous phrase such as “the number on the left.”
Tell Rayito what the result is supposed to mean. A total, a rate, and a running balance can share some inputs while requiring different formulas. The assistant can explain what is visible, but it should not assume the business meaning of an unlabeled column.
Build a dependency picture
In the example, quantity in column B and price in column C produce the total in column D. Two short connections are enough to make that relationship visible. There is no need to redraw the entire sheet or place a text label over every cell.
For a longer formula, break the calculation into meaningful intermediate results. First identify the selected range, then the filtering condition, then the final aggregation. Ask for one step at a time so you can compare the explanation with the formula bar rather than holding every nested expression in memory.
Check a row before copying anything
Use values you can calculate yourself. Three items at twelve each should produce thirty-six before any additional adjustments. If the displayed result disagrees, inspect the actual cell contents, number formats, and references. A number displayed as rounded may contain a more precise underlying value.
Next, inspect what happens when the formula moves one row. Relative references usually move with it; an absolute reference such as $F$1 keeps the same address when copied. Mixed references lock only a row or column. Ask why a reference needs to stay fixed before adding dollar signs everywhere.
Separate explanation from editing
You can ask Rayito to explain a formula without asking it to change the spreadsheet. If you do request an edit, make the destination and intended effect explicit. Check the proposed value and target before allowing the action, especially in a sheet shared with other people.
Keep a known example or an unchanged copy available for comparison. A formula that works in the first row may still fail on blank rows or unexpected text. Check those cases in the spreadsheet itself. Visual reasoning helps you select useful checks; it is not a substitute for seeing their actual results.
Ask about the relationship, not the syntax alone
A useful question includes the outcome you want and the part that surprises you. “Why does this total change when I copy it?” is more informative than “fix this formula.” If a reference points to another tab, open that context before accepting a diagnosis.
Rayito’s screen-based walkthrough can keep the explanation beside the relevant cells. You still choose whether the formula expresses the rule your work needs. When the rule is clear, the syntax becomes easier to evaluate and the next unusual result becomes easier to investigate.
