Operator Name + (Plus) Addition 1+1 - (Minus) Subtraction 2-1 - (Minus) Negation -5 * (asterisk) Multiplication 2*2 / (Slash) Division 9/3 % (Percent) Percent 15% ^ (Caret) Exponentiation 3^2 Comparative operators These operators return either true or false. Operator Name = (equal sign) Equal A1=B1 > (Greater than) Greater than A1>B1 < (Less than) Less than A1<B1 >= (Greater than or equal to) Greater than or equal to A1>=B1 <= (Less than or equal to) Less than or equal to A1<=B1 <> (Inequality) Inequality A1<>B1 Text operators The operator combines separate texts into one text. Operator Name & (And) text concatenation AND text concatenation AND "Sun" & "day" is "Sunday" Reference operators These operators return a cell range of zero, one or more cells. Range has the highest precedence, then intersection, and then finally union. Operator Name : (Colon) Range A1:C108 ! (Exclamation point) intersection operator Intersection SUM(A1:B6!B5:C12) Calculates the sum of all cells in the intersection; in this example, the result yields the sum of cells B5 and B6. ~ (Tilde) Concatenation or union Takes two references and returns a reference list, which is a concatenation of the left reference followed by the right reference. Double entries are referenced twice. See note below this table. Reference concatenation using a tilde character was implemented lately. When a formula with the tilde operator exists in a document that is opened in old versions of the software, an error is returned. A reference list is not allowed inside an array expression.
