Introduction to Excel

What is a spreadsheet? It is a matrix composed of rows and columns. Columns are identified by letters and rows are identified by numbers. Columns: A – Z, AA – AZ, BA – Bz,…

Cell & Range Cell: Intersection of row and column identified by specifying column and row coordinates. A1, B3 Range: A group of rectangular shape cells identified by specifying the upper left corner and the lower right corner. B2:D3, A1:A3

Enter Constant in a Cell Number: 2.345, -1000, (1000) With comma or $: 1,234, $1,234.56 Fraction: 1 7/9, 1/3 Percentage: 5.25% Date: mm/dd/yy If yy < 30  20yy. If yy>=30  19yy Time: Min:Sec 15:25 Date and time: mm/dd/yy min:sec Text

Enter Formula and Function in a Cell Begin with an “=“ Use operators: +, - , *, /, ^, ( ) to define a formula. Function: =SUM(A1:A3) Formula with function: =SUM(A1:A3) * 5 + B5/2 To display formulas: Formulas/Show Formulas

Cell Reference

Demo

Copy Formula Drag the source cell Copy/Paste

Cell Reference Relative cell reference: After copy, the formula will reference cells with the same relative position as the original formula. Example: Value in cell E6: C6*D6 Absolute Cell Reference: After copy, the formula still references the same cell as the original formula. Tax in cell F6: E6*$C$3

AnnualGrowthRate: 5% of the previous year AnnualGrowthRate: 5% of the previous year. Compute the forcasted sales for the next 5 years

Mixed Cell Reference $ColumnRow: $A1 Column$Row: A$1 Examples: =$A1
