16. 16 Mathematical Operations and Formulas Mathematical operations are the backbone of Excel Formulas are used to perform mathematical operations and arrive at a calculated result Must begin with an equals (=) sign Used to automate calculations that were done manually Lecture Notes Chapter 01 (CSIT 104)

17. 17 Operator Symbols and Order Precedence Operator symbols include:  Addition (+), Subtraction (-), Multiplication (*), and Division (/), Exponentiation (^) Order of Precedence controls the sequence in which arithmetic operations are performed:  Basic rules – anything in parenthesis performed first; then exponentiation, then multiplication and division; then addition and subtraction (PEMDAS)  Example: = 20 + 22 * (10 – 6) = 20 + 22 * 4 = 20 + 88 = 108 Lecture Notes Chapter 01 (CSIT 104)
