A simple formula is a mathematical expression with one operator, such as 7+9. A complex formula has more than one mathematical operator, such as 5+2*8. When there is more than one operation in a formula, the order of operations tells your spreadsheet which operation to calculate first.

A calculus (note the 'a' before calculus) is set of rules for manipulating formal symbols, like turning a numeric statement like 3 + 2 into 5, or turning a logic statement like into p. Mathematics is more general than that, and has much to do with proving that the rules of a particular calculus can be used.
