A few question for you to work on…

Spreadsheets can make math easy!

Example: Let’s say that you have 5 green skittles and Chad has 1.8 times more green skittles than you; how many green skittles does he have?

Entering formulas1. Select cell A-7 and type “Total”

Using formulas with data2. In cell B7 type “=B1+B2+B3+B4+B5”

and press enter.

Using formulas with dataNotice that when you click on the values you want to add up is puts in the name of the cell.

Let’s find the average

3. Select cell A8 and type in “Average”.

Using formulas with data

4. To find the average number of skittles per color we must divide the total number of skittles by the number of colors (5).

Using formulas with data5. Select cell B8. We already found

the total in B7, so in B8 type “=B7/5” and press enter.

Interesting…very interesting

Notice that if you change the number of any color you had, the total and average change automatically.
