1)  

 Evaluate:

7 + 4 ÷ 4 × 5

Answer: 12


SOLUTION 1 :

Order of operations:

1. Multiplication and division
2. Addition and subtraction

Step 1: Multiply and divide from left to right.

7 + 4 ÷ 4 × 5

7 + 1 × 5

7 + 1 × 5

7 + 5

 

Step 2: Add and subtract from left to right.

7 + 5

12

7 + 4 ÷ 4 × 5 = 12
 



2)  

 Evaluate:

8 × 8 – 2 × 2

Answer: 60


SOLUTION 1 :

Remember:

Order of operations:

1. Multiplication and division
2. Addition and subtraction

Step 1: Multiply and divide from left to right.

8 × 8 – 2 × 2

64 – 2 × 2

64 – 2 × 2

36 – 4

 

Step 2: Add and subtract from left to right.

64 – 4

60

So:

8 × 8 – 2 × 2 = 60
 



3)  

 Evaluate:

6 ÷ 3 + 3 + 5

Answer: 10


SOLUTION 1 :

Remember:

Order of operations:

1. Multiplication and division
