Introduction Calc is a spread sheet -- what are those?
First
of all, let’s look at what you can do with a spread sheet. You can
use it as a calculator, make invoices, makes budgets, create lists,
make an analysis tool for evalating odds etc., etc., etc... The
possibilities are infinite.
A spread sheet is basically a
bunch of cells aligned horizontally and vertically.
In
each of these cells you can but different kinds of information.
Examples:
- numbers
- text
- formulas
Numbers
are entered both as information and as basis for formulas.
"Text?
Isn't that for word processors?". Yes. And no. You wouldn't want
to use a spread sheet for heavy word processing, but you could use a
spread sheet to describe the numbers or formulas you have in y our
spread sheet. 
Formulas;
this is where the magic lies... Most formulas are easy to use, some
are a little less easy to use and some are almost easy to use ;-) You
use formulas to change a bunch of data into something more useful,
such as a sum, or to count the numbers you have entered, or the
average of number etc.
An example; if you have a list of
20 numbers, you can, literally, in a matter of seconds find both the
sum of them, the average, the largest number AND the smallest number.
Not impressed? You feel you could do that without formulas? Of course
you can. But what if you have 200 numbers in the list? You would
still use the same formulas AND use the same amount of time to get
the numbers mentioned! Still not convinced? OK -- try 20.000 numbers
in a list. Done in the same amount of time. Try that on a
calculator.
OK, so some good news. The above example is
from the real world, and it's true! And it's fairly easy to
accomplish. The best news is that you'll know how in an hour or so...
