SpreadSheets handle numbers EXCEL Click your left mouse button to proceed... Organize numbers in rows and columns Perform mathematical calculations – sum of numbers

Columns are named A - B - C... Click your left mouse button to proceed... ABCD

Rows are numbered 1 - 2 - 3... Click your left mouse button to proceed... ABCD 1 2 3 4 5

Intersection of Row and Column is a Cell Cell Address is ColumnRow Click your left mouse button to proceed... The highlighted cell is the “Current Cell” or the “Active Cell” ABCD 1 2 3 4 5 Cell A1

Move from Cell to Cell with the Arrow Keys Click your left mouse button to proceed... ABCD 1 2 3 4 5 Pressing the Down-Arrow Key moves one cell Down - from A1 to A2 Cell A2

Move from Cell to Cell with the Arrow Keys Click your left mouse button to proceed... ABCD 1 2 3 4 5 And... pressing the Right-Arrow Key moves one cell to the Right - from A2 to B2 Cell B2

Or... Click the Left Mouse Button on a cell to make it the Current Cell Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer was moved to Cell C4 and the Left Mouse Button was Clicked Cell C4

Cells Contain Data Text in a cell is called a Label Click your left mouse button to proceed... ABCD 1 2 3 4 5 By default, labels in a cell are left-justified within the cell Cell A1 contains the label: Delta Delta

Labels automatically spill over to the next cell if needed Click your left mouse button to proceed... ABCD 1 2 3 4 5 As long as cell B1 does not contain any data, the “spilled-over” text will display and print Cell A1 now contains the label: Delta College Delta College

Cells can also contain a Number Click your left mouse button to proceed... ABCD 1 2 3 4 5 By default, numbers in cells are right-justified within the cell Cell A1 contains the number: 123 123

Often, you need to format the number...... later Click your left mouse button to proceed... ABCD 1 2 3 4 5 Sometimes, the number will not appear formatted -- until you make it look “pretty” Cell A1 contains the number: 123.40 123.4

Cells can also contain a calculation, called a Formula Click your left mouse button to proceed... ABCD 1 2 3 4 5 Cell A1 contains the number 15 Cell A2 contains the number 12 Cell A3 will contain the sum of these two numbers 15 12

Formulas operate on cell addresses Click your left mouse button to proceed... ABCD 1 2 3 4 5 Cell A1 contains the number 15 Cell A2 contains the number 12 Cell A3 contains a formula Cell A3 says “This cell equals the number in Cell A1 added to the number in Cell A2” 15 12 =A1 + A2 Formulas begin with an = sign.

The Result of the formula appears in the cell Click your left mouse button to proceed... ABCD 1 2 3 4 5 Cell A1 contains the number 15 Cell A2 contains the number 12 Cell A3 contains a formula Cell A3 says “This cell equals the number in Cell A1 added to the number in Cell A2” 15 12 27 Result

Range of Cells Single Cell Adjacent Cells in a Row Adjacent Cells in a Column Adjacent Cells in a “Rectangle”

Click your left mouse button to proceed... ( A1 : A3 ) Colon () Beginning Cell Address Ending Cell Address

Click your left mouse button to proceed... Range of Cells Single Cell Adjacent Cells in a Row Adjacent Cells in a Column Adjacent Cells in a “Rectangle” ( A1 : A1 ) ( A1 : C1 ) ( B1 : B5 ) ( A1 : C3 )

Click your left mouse button to proceed... ABCD 1 2 3 4 5 Range of Cells Single Cell ( A1 : A1 )

Click your left mouse button to proceed... ABCD 1 2 3 4 5 Range of Cells Adjacent Cells in a Row ( A1 : C1 )

Click your left mouse button to proceed... ABCD 1 2 3 4 5 Range of Cells Adjacent Cells in a Column ( B1 : B5 )

Click your left mouse button to proceed... ABCD 1 2 3 4 5 Range of Cells Adjacent Cells in a “Rectangle” ( A1 : C3 )

Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer Select a Cell – click within it Pointer is an outlined PLUS sign Selected cell is outlined & has box in lower right

Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer Select multiple Cells – click within first one Pointer is an outlined PLUS sign Drag to select the rest Multiple cells are surrounded by border and box is in lower right corner -- Starting cell remains original color

Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer If pointer at the border of a cell and dragged Pointer is an Arrow on top of a 4-way + arrow Cell is MOVED to where you drop it

Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer If pointer at the border of a cell and dragged Pointer is an Arrow Cell is MOVED to where you drop it

Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer Select a Cell – click on box in lower right corner Pointer is a regular PLUS sign Drag to select multiple cells Delta

Click your left mouse button to proceed... ABCD 1 2 3 4 5 The Mouse Pointer Select a Cell – click on box in lower right corner Pointer is an regular PLUS sign Drag to select multiple cells – and automatically copy Delta

Click your left mouse button to proceed... ABCD 1 2 3 4 5 Range of Cells Define a Range of Cells by Highlighting it –Point and click WITHIN the first cell –Hold the mouse pointer and drag to the last cell ( A1 : C3 ) Important: Do not point at border of cell while defining a range

ABCD 1 2 3 4 5 Click your left mouse button to proceed... Range of Cells Define a Range of Cells by Highlighting it –Point and click WITHIN the first cell –Hold the mouse pointer and drag to the last cell –Release the mouse pointer ( A1 : C3 ) Important: Do not point at border of cell while defining a range

Click your left mouse button to proceed... Key the function in Cell A3 Point at the Box in the lower right corner of Cell A3 – your mouse pointer is a PLUS sign You can copy this function! ABCD 1 2 3 4 5 15 12 26 42 =SUM(A1:A2)

Click your left mouse button to proceed... Drag the box in the lower right corner from Cell A3 to Cell B3 to highlight the range (A3:B3) You can copy this formula! ABCD 1 2 3 4 5 15 12 26 42 =SUM(A1:A2) Highlight the range for the copy...

Click your left mouse button to proceed... You have copied the function You can copy this formula! ABCD 1 2 3 4 5 15 12 26 42 =SUM(A1:A2) =SUM(B1:B2) The formula is automatically copied from the first cell to the rest of the cells in the range

Click your left mouse button to proceed... Instead of summing Column A, you are summing Column B You copied the function one column to the right The Function Was Adjusted ABCD 1 2 3 4 5 15 12 26 42 =SUM(A1:A2)=SUM(B1:B2) The new formula is adjusted one column to the right This is called Relative Addressing A’s become B’s

Click your left mouse button to proceed... This is called Relative Addressing because the formulas are adjusted “relative” to how they were copied Of Course, the Cells Show the Results of the Formulas ABCD 1 2 3 4 5 15 12 26 42 27 68

Click your left mouse button to proceed... Key the function in Cell C1 Select the range (C1:C2) using the corner box Drag the corner box down to copy The Formula was copied down one row so the “1’s” become “2’s” You Can Also Sum In A Row ABCD 1 2 3 4 5 15 12 26 42 =SUM(A1:B1) =SUM(A2:B2) 1’s become 2’s

Click your left mouse button to proceed... The Results of the calculations are shown in the cells You Can Also Sum In A Row ABCD 1 2 3 4 5 15 12 26 42 41 54

Click your left mouse button to proceed... The Asterisk (*) is used for multiplication Here’s Some Multiplication ABCD 1 2 3 4 5 15 12 26 42 =A1 * B1 The formula in Cell C1 says “I’m equal to the number in Cell A1 multiplied by the number in Cell B1.

Click your left mouse button to proceed... The formula can be “Copied-Down” by dragging the corner box... Here’s Some Multiplication ABCD 1 2 3 4 5 15 12 26 42 =A1 * B1 The “1’s” become “2’s” so you end up multiplying Cell A2 by Cell B2 and putting that result in Cell C2 =A2 * B2

Click your left mouse button to proceed... As usual, the results are in the cells Here’s Some Multiplication ABCD 1 2 3 4 5 15 12 26 42 390 504
