3. All 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

4. All Formulas are Not Equal =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. =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.

5. Multiplication 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!
