1. Overview of Spreadsheets
EXCEL SPREADSHEET

2. What is a spreadsheet?
A grid of rows and columns in which you enter text, numbers, and the results of calculations; the main purpose of a spreadsheet is to solve problems that involve numbers
A grid is a pattern of regularly spaced horizontal and vertical lines
Horizontal
Vertical

3. Making calculations 1 Add these numbers: 2 5 3 The answer is 10.
That was easy!

4. Making calculations 2 Add the following amounts of money: $25.00
$19.25
$77.77
$94.89
The answer is $
This one is a bit more difficult, but you can still do it easily!

5. Making calculations 3-1 Solve the following equation:
A1 + A2 + A3 – A4
(If A1 = 5, A2 = 9, A3 = 4, and A4 = 5)
The answer is 13.
This one took more time since you had to “plug” in the values.

6. Making calculations 3-2
Using the previous equation, let’s make some changes:
A1 + A2 + A3 – A4
If A1 = 5, A2 = 9, A3 = 4, and A4 = 5, then the answer is 13.
What if I change the value of A2 to 12?
The answer is 16.
What if I change the operation between A1 and A2?
Instead of addition, now it should be multiplication.
The answer is 59.
Now it is getting more difficult!
