# PE M/D A/S - Three Steps with Exponents

## PE M/D A/S - Three Steps with Exponents - How It Works - Video

### Example 1 Example 1:

Remember multiplication and division are the same magnitude as well as addition and subtraction. In this example we have to look inside the parenthesis first.

40 - (32 * 4)

=> 40 - (9 * 4) - Exponents

=> 40 - (36) - Multiplication

=> 4 - Subtraction

### Example 2 Example 2:

Remember multiplication and division are the same magnitude as well as addition and subtraction. In this example we have to look inside the parenthesis first.

20 ÷ (32 + 1)

=> 20 ÷ (9 + 1) - Exponents

=> 20 ÷ (10) - Addition

=> 2 - Division

### Example 3 Example 3:

Remember multiplication and division are the same magnitude as well as addition and subtraction. In this example we have to look inside the parenthesis first.

18 ÷ 32 - (3 + 4)2

=> 18 ÷ 32 - 72 - Addition

Here we can either square both numbers at the same time or different steps because there aren't anymore parenthesis.

=> 18 ÷ 9 - 72 - Addition

=> 18 ÷ 9 - 72 - Exponents

=> 18 ÷ 9 - 49 - Exponents

=> 2 - 49 - Division

=> -47 - Subtraction

### Example 4 Example 4:

Remember multiplication and division are the same magnitude as well as addition and subtraction. In this example we have to look inside the parenthesis first.

100 - 2(32 - 4)

=> 100 - 2(9 - 4) - Exponents

=> 100 - 2(5) - Subtraction

Remember here there is an invisible multiplication sign in between the 2 and the 5.

=> 100 - 10 - Multiplication

=> 90 - Subtraction

### Example 5 Example 5:

Remember multiplication and division are the same magnitude as well as addition and subtraction. In this example we have to look inside the parenthesis first. Since we have two, we can do both at the same time or different steps.

(3 + 4)2 - (4 * 2)

=> 72 - (4 * 2) - Addition

=> 72 - 8 - Multiplication

=> 49 - 8 - Exponents

=> 41 - Subtraction
