Answer 2

Order of Operations and Expression Evaluation

To solve the given expressions and determine their values, we need to follow the order of operations, also known as the PEMDAS rule. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's evaluate each expression step by step:

1. 5 + 8 * 16 = According to the order of operations, we need to perform the multiplication before the addition. So, we multiply 8 by 16 first and then add 5. 8 * 16 = 128 5 + 128 = 133

Therefore, the value of the expression is 133.

2. 17 + 24 - 8 + 37 = Again, we follow the order of operations. First, we perform addition and subtraction from left to right. 17 + 24 = 41 41 - 8 = 33 33 + 37 = 70

Therefore, the value of the expression is 70.

3. 74 - 39 + 15 - 6 = Following the order of operations, we perform addition and subtraction from left to right. 74 - 39 = 35 35 + 15 = 50 50 - 6 = 44

Therefore, the value of the expression is 44.

4. 72 : 8 · 3 = According to the order of operations, we need to perform division before multiplication. So, we divide 72 by 8 first and then multiply the result by 3. 72 : 8 = 9 9 · 3 = 27

Therefore, the value of the expression is 27.

5. 48 : 6 · 3 : 4 = Again, we follow the order of operations. First, we perform division from left to right, and then multiplication. 48 : 6 = 8 8 · 3 = 24 24 : 4 = 6

Therefore, the value of the expression is 6.

6. 32 : 4 · 2 : 1 = Following the order of operations, we perform division from left to right. 32 : 4 = 8 8 · 2 = 16 16 : 1 = 16

Therefore, the value of the expression is 16.

7. 53 - 8 · 6 = According to the order of operations, we need to perform multiplication before subtraction. So, we multiply 8 by 6 first and then subtract the result from 53. 8 · 6 = 48 53 - 48 = 5

Therefore, the value of the expression is 5.

8. 36 + 42 : 7 = Again, we follow the order of operations. First, we perform division, and then addition. 42 : 7 = 6 36 + 6 = 42

Therefore, the value of the expression is 42.

9. 62 - 9 · 4 + 5 = Following the order of operations, we perform multiplication and subtraction from left to right, and then addition. 9 · 4 = 36 62 - 36 = 26 26 + 5 = 31

Therefore, the value of the expression is 31.

To summarize, the values of the given expressions are as follows: 1. 5 + 8 * 16 = 133 2. 17 + 24 - 8 + 37 = 70 3. 74 - 39 + 15 - 6 = 44 4. 72 : 8 · 3 = 27 5. 48 : 6 · 3 : 4 = 6 6. 32 : 4 · 2 : 1 = 16 7. 53 - 8 · 6 = 5 8. 36 + 42 : 7 = 42 9. 62 - 9 · 4 + 5 = 31
