SpreadSheets handle numbers

EXCEL


Organize numbers in rows and columns

Perform mathematical calculations – sum of numbers

The SpreadSheet


Columns are named A - B - C . . .


A B C D

Rows are numbered 1 - 2 - 3 . . .

By default, labels in a cell are left-justified within the cell

Cell A1 contains the label: Delta

Labels automatically spill overto the next cell if needed

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

By default, numbers in cells are right-justified within the cell

Cell A1 contains the number: 123

Often, you need to format the number . . . . . . later

Sometimes, the number will not appear formatted -- until you make it look “pretty”

Cell A1 contains the number: 123.40

Cells can also contain a calculation, called a Formula

Cell A1 contains the number 15

Cell A2 contains the number 12

Cell A3 will contain the sum of these two numbers

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”

=A1 + A2

Formulas begin with an = sign.

The Result of the formula appears in the cell

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


Instead of summing Column A, you are summing Column B

You copied the function one column to the right

The Function Was Adjusted

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


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

=A1 * B1The “1’s” become “2’s” so you end up multiplying Cell A2 by Cell B2 and putting that result in Cell C2

=A2 * B2
