IMPORTANT QUESTIONS!
 What should you be thinking about when
solving a math problem?
Why is it important to use the order of
operations?
What operations are used in solving these
kinds of problems?
What is the correct order to the steps of
the order of operations?
ALL ABOUT

THE
ORDER
OF
OPERATIONS!
What is an operation?

When Solving a multi-operation
math problem, how do you
know what to calculate first?
P⇨ Stands for Parentheses!
 Do everything in the parentheses first!
 This is the first step of the order of operations.
E⇨ Stands for Exponents (Powers and Roots)!
 This is the second step to the order of operations.
 This comes after everything in the parentheses, but before
multiplying, dividing, adding and subtracting.
M⇨ Stands for Multiplication!
D⇨ Stands for Division!
 Multiplication and division, combined, is the third step of the
order of operations.
These come after everything in parentheses and all exponents,
but before addition and subtraction.
A⇨ Stands for Addition!
S⇨ Stands for Subtraction!
 Addition and subtraction, combined, is the last step of the
order of operations.
These come after you have completed everything in
parentheses, all exponents, and all multiplication and division.
ALWAYS multiply and divide from left to
right!!!
Also, ALWAYS add and subtract from
left to right!!!
Chapter 111.23, Subchapter B- Middle School
(b) Knowledge and Skills.
(1) Number, operation, and quantitative reasoning. The student represents and uses numbers in a variety of
equivalent forms. The student is expected to:
(A) compare and order integers and positive rational numbers;
(B) convert between fractions, decimals, whole numbers, and percents mentally, on paper, or with a
calculator; and
(C) represent squares and square roots using geometric models.
(2) Number, operation, and quantitative reasoning. The student adds, subtracts, multiplies, or divides to solve
problems and justify solutions. The student is expected to:
(A) represent multiplication and division situations involving fractions and decimals with models,
including concrete objects, pictures, words, and numbers;
(B) use addition, subtraction, multiplication, and division to solve problems involving fractions
decimals;
(C) use models, such as concrete objects, pictorial models, and number lines, to add, subtract,
multiply, and divide integers and connect the actions to algorithms;
(D) use division to find unit rates and ratios in proportional relationships such as speed, density,
price, recipes, and student-teacher ratio;
(E) simplify numerical expressions involving order of operations and exponents;
(F) select and use appropriate operations to solve problems and justify the selections; and
(G) determine the reasonableness of a solution to a problem.
