If: This formula allows you to perform different actions based on whether a condition is true or false. For example, you can use the formula
=IF(A1>B1, "A is greater","B is greater")
to compare the values in cells A1 and B1 and display a message depending on which value is greater. 
VLOOKUP: This formula searches for a value in a table and returns a corresponding value from a different column in the same row. For example, you can use the formula

to search for the value in cell A1 in the range B1:C5 and return the value from the second column (C) in the same row.

MAX: This formula returns the maximum value in a range of cells. To find the maximum value in cells A1 through A5, for example, use the formula =MAX(A1:A5).

MIN: This formula returns the minimum value in a range of cells. To find the minimum value in cells A1 through A5, for example, use the formula =MIN(A1:A5).

Today: This formula returns the current date. You can use it to insert the current date into a cell, or you can use it in calculations. For example, you can use the formula
=TODAY()+7
to add 7 days to the current date.
