Copy, Cut, Paste, and Cell Addressing
In Excel, you can copy data from one area of a worksheet and place the data you copied anywhere in the same or another worksheet. In other words, after you type information into a worksheet, if you want to place the same information somewhere else, you do not have to retype the information. You simple copy it and then paste it in the new location.
You can use Excel's Cut feature to remove information from a worksheet. Then you can use the Paste feature to place the information you cut anywhere in the same or another worksheet. In other words, you can move information from one place in a worksheet to another place in the same or different worksheet by using the Cut and Paste features.
Microsoft Excel records cell addresses in formulas in three different ways, called absolute, relative, and mixed. The way a formula is recorded is important when you copy it. With relative cell addressing, when you copy a formula from one area of the worksheet to another, Excel records the position of the cell relative to the cell that originally contained the formula. With absolute cell addressing, when you copy a formula from one area of the worksheet to another, Excel references the same cells, no matter where you copy the formula. You can use mixed cell addressing to keep the row constant while the column changes, or vice versa.
For example, if a simple addition formula in cell C1 "=(A1+B1)" is copied to cell C2, the formula would change to "=(A2+B2)" to reflect the new row.
To prevent this change, cells must be called by absolute referencing and this is accomplished by placing dollar signs "$" within the cell addresses in the formula.
Continuing the previous example, the formula in cell C1 would read "=($A$1+$B$1)" if the value of cell C2 should be the sum of cells A1 and B1.
Both the column and row of both cells are absolute and will not change when copied. Mixed referencing can also be used where only the row OR column fixed. For example, in the formula "=(A$1+$B2)", the row of cell A1 is fixed and the column of cell B2 is fixed.
Exercise 2
The exercise below uses mixed referencing. The formula for Cell F6 is displayed in the formula bar.
We have multiplied the price of the widget in Cell E3 by the number sold in Cell D3.
Cell E3 is an absolute reference because the price of the widgets will not change, only the quantity sold.
The formula for Cell F7 is displayed in the function bar.
The price of the widgets did not change, so the price is set as an absolute reference.
When the formula was copied to cell F7, Excel automatically changed the formula to reflect the new value of Cell D4, but retained the absolute reference in Cell E3.
Absolute Cell Addressing
You make a cell address an absolute cell address by placing a dollar sign in front of the row and column identifiers. You can do this automatically by using the F4 key. To illustrate:
Move to cell C12.
Type =.
Click cell C9.
Press F4. Dollar signs appear before the C and the 9.
Type +.
Click cell C10.
Press F4. Dollar signs appear before the C and the 10.
Type +.
Click cell C11.
Press F4. Dollar signs appear before the C and the 11.
Click the check mark on the formula bar. Excel records the formula in cell C12.
