3. Insert and Delete Insert Rows and Columns is used to add a row or column in a worksheet. Delete Rows and Columns is used to remove a column or row in a worksheet.

4. Filling, Splitting and Freezing Fill or Filling copies data to adjacent cells; is especially good for copying formulas. Split or Splitting divides the screen into two or four parts. ◦ It allows you to view different parts of a large worksheet at the same time. Cut is used to remove or move a cell. Copy is used to make a duplicate of a cell. Paste is used to move a cell from the clipboard to the worksheet. Freezing keeps row or column titles on the screen no matter where you scroll in the worksheet.

5. Cell References Relative adjusts the row and column to its new location when copied or moved. ◦ D14 is an example of a relative cell reference. Mixed adjusts either the row or column to its new location when copied or moved. ◦ D$14 is an example of a mixed cell reference. Absolute does not adjust the row and column to its new location when copied or moved. ◦ $D$14 is an example of an absolute cell reference. To change a cell so that the row or column does not change, you should put a $ in front of either the row number or column letter. To change a cell so that it does not change at all, you must put a $ in front of both the column and row. A quick and easy way to change a cell or range from relative to absolute to mixed and back to relative is F4.

6. Formula Features Formulas are equations that perform calculations on values in your worksheet. ◦ In Excel, formulas begin with =. Autosum adds the values that are contained in a range of cells. ◦ ∑ is the symbol that indicates autosum feature. Sum is a function used to add the values that are contained in a range of cells. ◦ =SUM(B4:B8)

7. Formula Features Operator - Symbols such as *, +, -, and / are examples of operators. Operand – The numbers or cell references used in formulas. ◦ = B4 * 8B4 and 8 are operands; * is an operator. Order of Operations or Order of Evaluation The order of evaluation (order of operation) in order is 1.Parenthesis P 2.Exponents E 3.Multiplication/division MD 4.Addition/subtraction AS P lease E xcuse M y D ear A unt S ally!

8. Be able to write formulas: Write the formula to multiply the contents of A3 by B3. = A3 * B3 Add contents of cells C4 through C14. = SUM (C4:C14) Subtract the contents D10 from D8. = D8 – D10 Divide the contents E4 by F7. = E4 / F7 Raise the contents of cell G3 to the 3rd power. = G3 ^ 3

9. Be able to solve formulas: =5 * 4 +2 = 22 =5 * (4 + 2) = 30 =2 + 10 / 2 = 7 =(2 + 10) / 2 = 6 =2^ 2 + 4 = 8
