Main Functions and Formula used in Excel.

There are many pre-defined functions in Excel but the most important pre­defined functions are:
  • SUM function.
  • AVERAGE function
  • MAX function
  • MIN function
  • PRODUCT function
  • IF function
SUM Function
It is used to add numbers given as parameters. These may be numeric values or cell references. Its general syntax is:
SUM(numberl,number2, .,.) Where
numberl, number2,... : specifies arguments which you want to add.
Example, = SUM (3, 2) returns 5. Similarly, to add values of cell range Al to A30, the function is written as:
=SUM (A1:A30)
AVERAGE Function
It is used to calculate the average of values given as parameters. These may be numeric values or cell references. Its general syntax is:
AVERAGE (numberI, number2, ...) Where
numberl, number2,... : specifies arguments for which you want to
calculate average. For example. AVERAGI. (3, 2) returns 2.5. Similarly, to calculate average of values of cell range Al to A30. the function is written as:
=AVERAGE(A1:A30)
MAX Function
It returns the largest or maximum value from a list of values. The parameters may be numeric values or cell references. Its general syntax is:
MAX (numberl, number2, ...) Where
numberl, number2,... : specifies arguments from which you want to find maximum, for example, =MAX(3. 2,45,23) returns 45.
MIN Function
It returns the lowest or minimum value From a list of values. The parameters may be numeric values or cell references, its general syntax is:
MIN(number 1, number2….) Where
numberl, number2,... : specifies arguments from which you want to
find minimum. For example, =M1N(3, 2,45,23) returns 2.PRODUCT Function
It is used to multiply numbers given as parameters. These may be numeric values or cell references. Its general syntax is:
PRODUCT (number1 ,number2, ...) where
numberl, number2,... : specifies arguments which you want to multiply. For example, =PRODUCT (13, 2) returns 26. Similarly, to multiply values of cell range Al to A30, the function is written as:
=PRODUCT (A 1:A30).
