What is the order of operations?
This instruction is called the order of operations.
If all these rules continue, we all get the same correct answer!
First:
5 + (32) = 5 + 6 = 11
Which is correct?
For:
Brackets
orders (power and roots like square roots)
Order or index
Dividing and multiplication (left to right)
Add and subtract (left to right)
Solve with the operation
If there is only an operation, resolve it. correct?
15
Step 1: Solve both brackets:
105= 5
3= 6
Step 2: Add/ Multiply the numbers alone.
Example:
3²3=9
Very = 4 = 16
Example 4:
2 +5² 1: Solve the exponent first:
5 2: 2 + 25 = 27
Step by Step:
1. Clamp: (4 + 3) = 7
2. Exponent: 2²= 4
3. Multiply: 7‐4 = 28
4. Divide: 6・3 = 2
5. Sub: 282= 26
Left to Right
Example:
104 + 1 = 7

Order!
5 + 32= ___
(6 + 4) 2= __
23+4 = ___
3²3= __
(106）+ 4²= __
20・（5 + 5）2= ___
8 + 2（3 + 1）= __
93 + 2
20
10
9 + 6 = 15
4 + 16 = 20
20。 (3 + 1) = 4, 2 UES 8, 8 + 8 = 16
93 = 6, 22 = 4 = 10
