1. Glade Manual – Chapter 2 1 Naming Data Ranges: - default approach for multiplication: write formulas involving cell references e.g. =B2*C2 - To give meaningful name to an entire range of cells, we can write a formula involving the variable names e.g. =Price_Each*Quantity - Introduce “Named range” Method: 1. Select desired range (i.e. highlight it) 2. Select “Formula” “Define Name” 3. Change default name, if desired EECS 1520 -- Computer Use: Fundamentals

2. Glade Manual – Chapter 2 2 EECS 1520 -- Computer Use: Fundamentals Naming Data Ranges: - To use a named range in a formula Method: 1. Select first cell where formula is to be placed 2. type “=” symbol 3. Select “Formula” “Use In Formula”, select first operand (Price_Each) 4. type “*” symbol 5. Select “Formula” “Use In Formula”, select second operand (Quantity)

3. Glade Manual – Chapter 2 3 Absolute Cell Reference (Pg. 2-5 in Glade Manual Ch. 2): - “Lock” the column or row by putting a “$” in front of the column letter or row number EECS 1520 -- Computer Use: Fundamentals

4. Glade Manual – Chapter 2 4 Point-and-click technique to build a formula:  Should not touch the keyboard except when entering constants or operators  Expressions not involving functions, i.e. only cell references  Nested functions EECS 1520 -- Computer Use: Fundamentals

5. Glade Manual – Chapter 2 5 Exercise 3 (A Gas Equation Model)  Named ranges and formulas in Exercise 3 P = nRT/V becomes =n*R_*T/V P=nRT/(V-nb)-n 2 a/V 2 becomes =n*R_*T/(V-n*b)-n*n*a/(V*V) Excel formula Note: “R” is reserved in Excel for “row”, so we have to change name the variable “R” as R_ EECS 1520 -- Computer Use: Fundamentals

6. Glade Manual – Chapter 2 6 Exercise 4 (The Cobb-Douglas Model)  Named ranges and formulas in Exercise 4 L = (s/(fM a_machinery )) 1/a_labour becomes =(S/(f*M^a_machinery))^(1/a_labour) L = (K-M)/e becomes =(K-M)/e Excel formula EECS 1520 -- Computer Use: Fundamentals

7. Glade Manual – Chapter 2 7 - Notes :  To “Format a cell”: “Home” “Cells”“Format” “Format Cells”  To select “Formula View”: “Formulas” “Formula Auditing”“Show Formulas”  To edit or fine-tune a graph: Click on the graph Select “Chart Tools” Select “Layout” EECS 1520 -- Computer Use: Fundamentals
