Simple Math Calculations

REMEMBER all formulas start with an equal sign (=)

Symbol Example

Multiply * =B3*C5

Divide / =B3/C5

Add + =B3+C5

Subtract – =B3-C5

Order of Operations: 1) Parentheses 2)* / 3)+ –

Cell References/Address

Always use cell addresses when computing cell information!

Relative Reference – cell reference in formula changes as it is copied relative to the new cell

Absolute Reference – cell reference in formula does not change – must add $ (ex. $D$12)

Using AutoSum Feature

Used to quickly add a group of numbers

1. Put cursor in cell for answer

2. Click AutoSum button

3. Select range to add and press Enter

Number Styles

Comma/Number – (ex. 1,000)

Accounting/Currency – (ex. $1,000)

Percent – (ex. 0.2235 to 22.35%)

Date – Changes format as desiredMarch 21, 2009 or 3/21/09

(Right click – select Format Cells…)

Math Worksheet

For example, if a problem said:

Add cells B5 through D5

You would use AutoSum because you always use AutoSum when totaling a range—and the word through indicates a range

Or if a problem said:

Multiply A4 and B10 then subtract G9

You enter =A4*B10-G9 in the cell

Math Worksheet

Complete the worksheet on page 23 of your folder by writing the equation on the line next to the problem given.

Those examples on the previous slide would look like this:

1. B5 through D5 Use AutoSum

2. Multiply A4 and B10 then subtract G9 =A4*B10-G9
