What is a function? A function is a "named operation" Functions have parentheses parameters/arguments inside the parentheses Function Result =SUM(1,2,3,4,5) 15 =SUM(a1,b1,c1) a1+b1+c1 =SUM(9,a1,b2,5,c1) 9+a1+b2+5+c1 3/14/2019 CDC-4

Types of operations You can use any of the following operations in a formula: operation symbol example addition: + =a1+3 subtraction: - =100-b3 multiplication: * =a1*b1 division: / =d1/100 exponentiation ^ =a2^2 negation - =-a2+3 (same symbol as substraction) 3/14/2019 CDC-4

Order of operations When using several operations in one formula, Excel follows the order of operations for math. first: all parentheses - innermost first second: exponents (^) third: all multiplication (*) and division (/). Do these starting with the leftmost * or / and work to the right.( left to right) fourth: all addition (+) and subtraction (-). Do these starting with the leftmost + or - and work to the right.( left to right) 3/14/2019 CDC-4

Order of operations The value of 3 + 2 * 5 is 13 NOT 25! 3/14/2019 CDC-4
