ORDER OF OPERATIONS How to do a math problem with more than one operation in the correct order. Cornell notes: page 5

PEMDAS Remember the order by the phrase Please Excuse My Dear Aunt Sally

The “P” and “E” The “P” stands for items in parenthesis Do all items in the parenthesis first The “E” stands for Exponents Do anything that has a exponent (power) 8282

The “MD” Represents Multiply and Divide Do which ever one of these comes first in the problem Work these two operations from left to right 6 / 2 x 4 / 3

The “AS” Represents Add and Subtract Do which ever one of these comes first Work left to right

1) 5 + (12 – 3) 2) 8 – 3 2 + 7 3) 39 ÷ (9 + 4)

4) 10 + 8 ÷ 2 – 6 5) 15 10 3 6) 36 ÷ (1 + 2) 2 7) 3 10 4

8) (5 – 1) 3 ÷ 4 9) 14 + 3(7 -2) – 2 5

SCR Why does the order of operation matter? Write the SCR question in your notes – it is part of your homework each night. Topic sentence Use math vocabulary Use complete sentences and good grammar (NO IM) Correct solution Examples/Counter- examples
