In most computer programs there are several ways to do the same thing.

There are exceptions where an approach that will give you the correct answer may not hold when you do expand or modify your document.

All Formulas are Not EqualAll Formulas are Not Equal

For Example: =B2+B3+B4+B5+B6

Will add the numbers in cell B2 through B6 But it is not the same as

=sum(B2:B6) This will also add the numbers in cells B2 through

B6 But it will also adjust automatically if you add rows

between B2 and B6

For Example: =B2+B3+B4+B5+B6

Will add the numbers in cell B2 through B6 But it is not the same as

=sum(B2:B6) This will also add the numbers in cells B2 through

B6 But it will also adjust automatically if you add rows

between B2 and B6

=sum(B2:B6) is also shorter to type =sum(B2:B6) is also what you get when

you use autosum Remember, sum is only to be used for

addition.

MultiplicationMultiplication

Multiplication is easy! =Cell Name*Amount

For example =b5*2.3% Or =b5*.023 Either of these will give you the exact same answer.

Watch your decimal points! Most mistakes are due to wrong decimal point

location. Hint: If your taxes or reserve is higher than your

income for the column, you made a mistake!

Please!Please!

In this class we want you to use the range approach for addition. =sum(B2:B6)

It will help you later on as you expand your skills in Excel.

Tomorrow you will start your Practical on Excel.

Our Practical will be just like the exercises and practices we’ve been doing in class.

The only difference is that it will be graded as a test.
