3. ORDER OF OPERATIONS
How to do a math problem with more than one operation in the correct order.

4. What is P.E.M.D.A.S. and why do we need it?
P.E.M.D.A.S. is also know as the Order of Operations.
Order of Operations is the order in which you perform mathematical operations to solve an equation.
We need P.E.M.D.A.S. because it helps us solve equations properly and always the same way.
Remember: Calculate an equation in the wrong order and you will get the wrong answer.

5. arenthesis “( )” 6 (5+3) Used to group equations.
Parenthesis can also be shown as brackets.
”[ ] or { }”.
An example of an equation with parenthesis is:
6 (5+3)
Choose the proper way to solve the equation:
A. 6x5 =30
= 33
B. 5+3 =8
8 x 6 = 48
Answer:

6. Choose the proper way to solve the equation:
xponents “22” 2
5 x 2
Choose the proper way to solve the equation:
A. 2 = 4
4x5 = 20
B. 5 x 2 = 10
10 = 100
Answer:
Used to multiply the same number repeatedly.
Exponent tells how many times a base number is multiplied to itself.
5 = 5x5x5 =125
An example of an equation using exponents is: 2 3 2

7. (2 + 3) 82 The “P” and “E” The “P” stands for items in parenthesis
Do all items in the parenthesis first
(2 + 3)
The “E” stands for Exponents
Do anything that has a exponent (power) 82

8. ultiplication “x” 2 x 5 + 3 A. 5 x 3 = 15 15 + 2 = 17 B. 2 x 5 = 10
Use the table on the right to help you.
Multiplication is just a faster way to add.
Choose the proper way to solve the equation:
2 x 5 + 3
A. 5 x 3 = 15
= 17
B. 2 x 5 = 10
10+ 3 = 13
Answer:

9. Choose the correct way to solve the equation:
ivision “÷”
Choose the correct way to solve the equation:
A = 6
= 2
B = 3
3 + 2 = 5
Answer:
Division is splitting a larger number into smaller parts.
Remember to check your division with multiplication.
An example of an equation with division in it is:

10. 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

11. Choose the proper way to solve the equation
ddition “+”
It is tempting to want to solve addition first in an equation.
Remember: only solve addition first if it is in parenthesis.
An example of an equation with addition in it is:
Choose the proper way to solve the equation
( ) + 81 =?
A = 132.5
= 213.5
B = 100.5
= 213.5
Answer:

12. The proper way to solve this equation is:
ubtraction ”-”
74 – (12 - 4)
The proper way to solve this equation is:
A. 74 – 12 = 62
62 – 4 = 58
B. 12 – 4 = 8
74 – 8 = 66
Answer:
Subtraction is when you take away an equal or smaller amount from a number.
You can check your subtraction with addition.
An example of an equation with subtraction in it is:

13. The “Add & Subtract” 8 + 7 - 5 + 2 Represents Add and Subtract
Do which ever one of these comes first
Work left to right
