### Example Question #1 : Arithmetic

5 * (482 – 82) + 100 / (3 + 2)2  = ?

2016

2400

2004

66.7

21,746

2004

Explanation:

Order of operations: "PEMDAS” or "Please Excuse My Dear Aunt Sally"

"Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

5 * (482 – 82) + 100 / (3 + 2)2  = ?

5 * (400) + 100 / (5) 2  =

2000 + 100 / 25 =

2000 + 4 = 2004

### Example Question #1 : Order Of Operations

Evaluate:

–1 + 2 * –3

–7

7

5

–3

3

–7

Explanation:

First you perform multiplication 2 * –3 = –6

Then you add –1 which gives you -7.

### Example Question #1 : Order Of Operations

Evaluate:

10 – 11 * (–1)2

–21

1

0

–1

21

–1

Explanation:

Evaluate the exponent, then distribute, then add.

### Example Question #1 : Arithmetic

Evaluate the expression:

(2 + 2)– 1

16

15

7

4

1

15

Explanation:

First you perform the operation in the parentheses and then you multiply the exponent; after that, subtract one.

### Example Question #1 : Order Of Operations

Evaluate:

(–1) + (2)2 * (–3)

–9

13

–13

–3

9

–13

Explanation:

First you evaluate the exponent. Then you multiply it by (–3) which gives you –12. Add –1 makes it –13.

### Example Question #2 : Order Of Operations

Solve the following equation:

(9 + 1) * (42 + 2) * (72 + 1) / 2 = ?

1014.5

4500

9000

39

1500

4500

Explanation:

Order of operations: "PEMDAS” or "Please Excuse My Dear Aunt Sally"

"Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

(9 + 1) * (42 + 2) * (72 + 1) / 2 =

(10) * (16 + 2) * (49 + 1) / 2 =

(10) * (18) * (50) / 2 =

9000/2 = 4500

### Example Question #2 : Order Of Operations

Solve the following equation:

(4 * 12) / (5 + 6 + 1) + 72 + (2 * 1 + 2)3 = ?

140

126

90.6

86

98.6

140

Explanation:

Order of operations: "PEMDAS” or "Please Excuse My Dear Aunt Sally"

"Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

(4 * 12) / (5 + 6 + 1) + 72 + (2 * 1 + 2)3 =

(48)/(12) + 72 + (2 + 2)3 =

(48)/(12) + 72 + (4) 3 =

(48)/(12) + 72 + 64 =

4 + 72 + 64 = 140

### Example Question #2 : Arithmetic

Solve: 4 + 2 * 4 = ?

10

24

14

12

32

12

Explanation:

To solve you must use the order of operations PEMDAS.
Multiplication comes first 4 * 2 = 8. Then add 4 + 8 = 12.

### Example Question #1 : How To Find Order Of Operations

The operation ¤ is defined as “cube the number that is to the right of the ¤ and subtract the result from the number that is to the left of ¤.” What is the value of 100 ¤  (5 ¤ 1)?

86

16

64

36

25

36

Explanation:

Starting inside the parentheses, cube the number to the right of the symbol, which is 1, and then subtract that from the number to the left of the symbol, 5, to get 4. Then we perform the same operation by cubing 4 to get 64, and then subtracting that from 100 to get 36.

### Example Question #1 : Order Of Operations

The expression is equivalent to:      In order to find the equivalent expression, distribute to get .
