Final answer:
Absolute cell referencing in spreadsheets maintains a constant reference to a specific cell when a general formula is copied to multiple cells. The symbol for absolute referencing is the dollar sign ($), which is added before the column letter and row number.
Step-by-step explanation:
The question asks about the use of absolute cell referencing in spreadsheets. When applying a general formula repeatedly across different cells but wish to maintain reference to the same cell in each formula, you should use absolute cell referencing. This is done by adding a dollar sign ($) before the column letter and/or row number, for example, $A$1 would make both the column and row absolute. If you want to apply the same operation to a different set of numbers but keep one cell constant (for example, if you're applying a constant multiplier or divider), absolute referencing is essential.
