SUM
Sums the contents of cells.
Syntax:
SUM(number1; number2; ... number30)
number1 to number30 are up to 30 numbers or ranges of numbers whose sum is to be calculated.
SUM can also be used to sum cells where a specified condition is true - see Conditional Counting and Summation.
Example:
SUM(2; 3; 4) | returns 9, because 2+3+4 = 9. |
SUM(B1:B3) | where cells B1, B2, B3 contain 1.1, 2.2, 3.3 returns 6.6. |
