Input method of absolute reference: 1. Open the spreadsheet software; 2. Enter a formula in the cell, and use the $ symbol to mark the place where absolute reference is required; 3. In the formula, select the absolute reference The referenced cell, and then add a $ sign before or after it; 4. If you only need to fix a certain row or column instead of the entire cell, you can add a $ sign before or after the row number or column number; 5. Enter the complete After entering the formula, press the Enter key to calculate the formula and display the result.

Absolute Reference is a feature used in spreadsheet software that allows a fixed cell to be referenced in a formula without The referenced cells change as formulas are copied and pasted.

In absolute references, cell references are represented by the $ symbol. The $ symbol is placed before the row or column number to indicate that the section is an absolute reference. For example, $A$1 represents an absolute reference to cell A1, $A1 represents an absolute reference to a cell in column A, row 1, and A$1 represents an absolute reference to a cell in row 1, column A.

The input method for absolute references is as follows:

Open spreadsheet software, such as Microsoft Excel or Google Sheets.

Enter a formula in the cell, and use the $ symbol to mark where an absolute reference is required.

In the formula, select the cell that needs an absolute reference, and then add a $ sign before or after it. For example, if you want to reference cell A1, you would enter $A$1 in the formula.

If you only need to fix a certain row or column instead of the entire cell, you can add a $ sign before or after the row number or column number. For example, if you want to reference the entire column A, you can enter $A1 in the formula so that the reference to column A remains unchanged when you copy and paste the formula.

After entering the complete formula, press the Enter key to calculate the formula and display the result.

The absolute reference input method can help users keep the references of certain cells unchanged when copying and pasting formulas, which is very useful when processing large amounts of data and performing complex calculations. By using absolute references, users can easily analyze and manipulate data without having to manually change cell references in formulas.
