Basic Formulas C.Multiply – Formula is =cell 1*cell4 Example: =a1*a4 will multiply the value in cell a1 by the value in a4 7IT: PIT: Basic Spreadsheet Formulas Copyright © Texas Education Agency, All rights reserved.

Basic Formulas D.Divide – Formula is =cell 1/cell4 Example: =a1/a4 will divide the value in cell a1 by the value in a4 8IT: PIT: Basic Spreadsheet Formulas Copyright © Texas Education Agency, All rights reserved.

Basic Formulas E. Relative Vs. Absolute Cell References Relative cell reference identifies the location of a cell and changes when the formula is copied and pasted to other cells. An absolute cell reference does not change. 9IT: PIT: Basic Spreadsheet Formulas Copyright © Texas Education Agency, All rights reserved.
