The first step of the following problem:
7 x 2 x ( 6 - 2 )
Parentheses: 6-2
-22 + (8-12) =
-8
What is the saying we use to remember the correct Order of Operations?
Please Excuse My Dear Aunt Sally
After simplifying the parentheses, what's the next step?
(13 + 4 ) + 10 ÷ 5
Divide: 10 ÷ 5
-3 x 6 / (-2) =
9
Name 2 operations that occur at the same time
Addition/Subtraction or Multiplication/Division
What is the third step?
(12 +24 ) ÷ ( 0 + 3 ) + 22
After completing the parentheses (steps 1&2), simplify the exponent.
18 / (-2) x 4 - 6 =
-42
What's the second step? How do you know?
8 ÷ (10 - 2 ) x 2
You need to follow PEMDAS and simplify the operations left to right. After the parentheses, division would be next.
-32 + (20 - 22) -11 X 2 =
-15
Why is it important to know PEMDAS as a mathematican?
So everyone solve a problem the same (correct) way.
What's the 3rd step?
(20 + 5 ) x 12 + 6
Add 6 to the product of 25 and 12
-10 - (3 X (-2)2) - (2 - 52) =
1
