The most important mathematical functions Lecture -8- By lec. (Eng.) Hind Basil University of technology Department of Materials Engineering

The most important mathematical functions

The function name The general formula for the function Example Sum =SUM(A1:A6) =SUM(A1,D2,B5 ) Find the total range Find the sum of the values separate Average Average(A1:A6)= Find the mean Count=Count(A1:A6) To calculate the number of digits in a range Maximum Value =Max(A1:A6) Maximum value within the range Minimum Value=Min(A1:A6) The minimum value within the range

The general formula for the function Purpose =POWER(A1 ;2) Function of power or exponent =SQRT(A1) Returns the square root =INT(A2) Approximation to the nearest integer The most important mathematical functions

The general formula for the function Purpose =Date() Insert the date =Today()Return today's date =Now() The return of today's date and the current time The most important functions of the date and time

The general formula for the function Purpose =LEN(D4) Calculates the number of characters in the cell =TRIM(A4) Reduce the blanks for the single digits =UPPER(F6)Transition from small to large =LOWER(F7)Transition from large to small The most important functions textual

The most important functions of the logic Function of IF =IF(logical_test ; value_if_true; value_if_false) Example: =IF(A1>=60;”YES”;”NO”)
