How to do cell references
Cell references in formulas can be created by manually typing the cell name or address directly into the formula bar (e.g., "=A1+B1"), or by selecting the desired cell(s) while typing the formula.
These references link formulas to specific cell values or ranges, allowing for dynamic calculations based on the content of those cells. Cell references provide flexibility, automatically updating formula results when referenced cell values change.
