This refers to the order of operations to perform when doing complex equations.
PEMDAS
Parentheses - first (from the inside out)
Exponents second (unless they are inside the parentheses)
Multiplication and Division third
Addition and Subtraction from left to right last(unless they are inside parentheses)
examples:
4-2+1 =3 addition and subtraction from left to right
4-(2+1) = 1 parentheses says do the addition first
4+3x2 = 10 multiplication first
(4+3)x2 = 14 Parentheses first
4e3+5x 4-2e3 = -82 exponents first, multiplication, then addition/subtraction
left to right
(4e3 +5)x(4-2)E3 = 552 parentheses first, but exponent inside parentheses
comes first 4e3=64, then add the 5, then 4-2=2, then do the
exponent outside parentheses 2e3=8, then multiply 69 x 8 = 552
Aunt before Sally Addition before subtraction
Please Excuse My Dear Aunt Sally (PEMDAS) is pretty much what Order of Operations is. It means Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
PEMDAS Please Excuse My Dear Aunt Sally
parenthesis, exponents, multiplication division, addition, subtraction
please excuse my dear aunt sally is in math this is when u have problems like 8 multiply 9 dived 8 u would multiply first because the m is before the d in pleases excuse my dear aunt sally that pembas thing helps u to know what u do first im in 6th grade and i know this that's sad whoever u r
Please Excuse My Dear Aunt Susie
Please Excuse My Dear Aunt Sally is a phrase used to remember the steps of the order of operations in order. Parentheses (please) Exponents (excuse) My (multiplication) Dear (division) Aunt (addition) Sally (subtraction)
its actually "please excuse my dear aunt sally" i dont know who invented it and i dont know why you would want to know
you farted;/
Please Excuse My Dear Aunt Sally.
Please Excuse My Dear Aunt Sally is an acronym to remember the order of operations in algebraic equations. It stands for Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
