This document discusses complex formulas in Microsoft Excel, including: 1. Complex formulas contain more than one mathematical operation, as opposed to simple formulas which only contain one operation. The order of operations must be followed when writing complex formulas. 2. The order of operations in Excel is: parentheses, exponents, multiplication/division (from left to right), and addition/subtraction (from left to right). 3. Formulas can contain absolute, relative, or mixed references. Absolute references keep the row and column constant when copied, relative references change the row and column, and mixed references are a combination.

- 1. Microsoft Excel Terminologies By: Mr. Jumari U. Mercullo
- 3. CREATING COMPLEX FORMULA • Excel is a spreadsheet application that can help you calculate and analyze numerical information. • household budget • company finances • inventory • and many more
- 4. CREATING COMPLEX FORMULA • In this lesson, you will learn how to write complex formulas in Excel following the order of operations. • relative referencing • cell referencing • absolute referencing • Mixed referencing • range of cell referencing
- 5. COMPLEX FORMULA • Simple formulas have one mathematical operation, such as 5+5. • Complex formulas have more than one mathematical operation, such as 5+52. • Order of operation should be determined.
- 6. ORDER OF OPERATIONS • Excel calculates formulas based on the following order of operations: 1. Operations enclosed in parentheses 2. Exponential calculations (to the power of) 3. Multiplication and division, whichever comes first 4. Addition and subtraction, whichever comes first
- 7. MNEMONIC OF OPERATIONS • A mnemonic that can help you remember the order is : • Please Excuse My Dear Aunt Sally • Parentheses, Exponent, Multiplication, Division, Addition and Subtraction () ^ * / + -
- 8. ORDER OF OPERATION EXAMPLE • The following example demonstrates how to use the order of operations to calculate a formula:
- 9. CREATING COMPLEX FORMULA • In this example, we will use cell references in addition to actual values, to create a complex formula that will add tax to the nursery order.
- 10. WORKING WITH CELL REFERENCES • In order to maintain accurate formulas, it is necessary to understand how cell references respond when you copy or fill them to new cells in the worksheet. • Excel will interpret cell references as either relative, absolute and mixed referencing.
- 11. WORKING WITH RELATIVE REFERENCE • By default, references. cell references are relative • When copied or filled, they change based on the relative position of rows and columns. NOTE: If you copy a formula =(A1+B1) into row 2, the formula will change to become =(A2+B2).
- 12. WORKING WITH RELATIVE REFERENCE • Select the first cell where you want to enter the formula (for example, B4). • Enter the formula to calculate the value you want (for example, add B2+B3).
- 13. WORKING WITH RELATIVE REFERENCE • Press Enter. The formula will be calculated. • Select the cell you want to copy (for example, B4) and click on the Copy. • Your formula is copied to the selected cells as a relative reference (C4=C2+C3, D4=D2+D3, E4=E2+E3, etc.) and the values are calculated.
- 14. WORKING WITH ABSOLUTE REFERENCES • Absolute references, on the other hand, do not change when they are copied or filled and are used when you want the values to stay the same. • NOTE: If you copy a formula =($A$1+$B$1) into row 2, the formula will still be =($A$1+$B$1).
- 15. WORKING WITH ABSOLUTE REFERENCES • An absolute reference is designated in the formula by the addition of a dollar sign ($). • It can precede the column reference, the row reference, or both.
- 16. WORKING WITH ABSOLUTE REFERENCES • Select the first cell where you want to enter the formula (for example, C4) • Click on the cell that contains the first value you want in the formula (for example, B4).
- 17. WORKING WITH ABSOLUTE REFERENCES • Type the first mathematical operator (for example, the multiplication sign). • Type the dollar sign ($) and enter the column letter of the cell you are making an absolute reference to (for example, B).
- 18. WORKING WITH ABSOLUTE REFERENCES • Select the cell you want to copy (for example, C4) and click on the Copy. • Select the cells where you want to paste the formula and click on the Paste. • Your formula is copied to the selected cells using the absolute reference (C5=B5*$B$1, C6=B6*$B$1, etc.) and your values are calculated.
- 19. WORKING WITH CELL REFERENCES • Mixed references, is a combination of relative reference and absolute reference. • NOTE: If you copy a formula =($A$1+B1) into row 2, the formula will change and become =($A$1+B2).
- 20. WORKING WITH CELL REFERENCES • Cell range, is a tool in excel which lets you group cells from your beginning cell to your last cell and perform operations with those grouped cells. • Symbol used in cell range is ( : ) which means to.
