1. (Fundamental) Order of Operations
The order-
Parenthesis
Exponents
Multiply
Divide
Add
Subtract

2. A way to Remember Please……………Parenthesis Excuse…………..Exponents
My………………..Multiply
Dear……………..Divide
Aunt……………..Add
Sally……………..Subtract
PEMDAS

3. Example 3 + 22 x (4x3) ÷ 4 = ____ What do you do first?
What do you do second?
What do you do third?
What do you do fourth?

4. 1. The 1st thing to be done in any math problem is anything in grouping symbols.
-grouping symbols include the following:
1. ( ) parenthesis
2. [ ] brackets
3. { } braces

5. example 3 + 22 x (4x3) ÷ 4 = ____ do (4x3) first = 12
left with x 12 ÷ 4 = ____

6. Exponents 2. The 2nd thing to be done in any math problem is Exponents
Exponent exponent
base
said 2 to the 2nd power ~ Exponential Form

7. 22
22 means to multiply the base times itself the number of times given by the exponent
(2, 2s multiplied together)
22 = 2 x 2 = 4

8. Special Exponents 32 -> said 3 to the 2nd power or 3 squared
40=1
Any number to the power of 0 is always 1

9. Multiply and Divide Go in order from left to right 3+4x12 ÷4=
First do 4x12=48
3+48 ÷4=
Then you divide 48 ÷4=12

10. Add and Subtract 3+12=15 Your answer is 15
Now that wasn’t so hard now was it!

11. Examples 19+6x2 ÷4 19+3=22 22 is your answer! (52-6)+6x2 ÷4= (52-6)=
Try This on Your Own
(52-6)+6x2 ÷4=
(52-6)=
52=5x5=25
25-6=19 (always do everything in the parenthesis first)
19+6x2 ÷4
6x2=12
19+12 ÷4=
12 ÷4=3
19+3=22
22 is your answer!

12. More Examples Okay, lets try this one! (15 ÷5)x9+2-(5+3 ÷2)=
Looks a bit harder doesn’t it.
(15 ÷5)=3 and (5+3 ÷2)=4
3x9+2-4
3x9=27
27+2-4
27+2=29
29-4=25
Your answer is 25!
