After following the order of operations and calculating (27 \times 36, we find that the result is 972. Adding 28 to this result gives us 1000. Thus, the correct answer is B. 1000.
;
First, multiply 27 by 36 : 27 × 36 = 972 .
Then, add 28 to the result: 28 + 972 = 1000 .
The correct answer is 1000 .
Therefore, the final answer is 1000 .
Explanation
Understanding the Problem We are given the expression 28 + 27 × 36 and asked to evaluate it and select the correct answer from the given options.
Applying Order of Operations According to the order of operations (PEMDAS/BODMAS), we must perform multiplication before addition. So, we first calculate 27 × 36 .
Performing Multiplication The result of the multiplication is 27 × 36 = 972 .
Performing Addition Now, we perform the addition: 28 + 972 = 1000 .
Selecting the Correct Answer Comparing the result with the given options, we see that the correct answer is B. 1000.
Examples
Understanding the order of operations is crucial in many real-life scenarios, such as calculating expenses. For example, if you buy 3 items costing $5 each and have a discount of $2, the total cost is calculated as 3 × 5 − 2 = 13 . This is different from 3 × ( 5 − 2 ) = 9 , which would be the cost if the discount applied to each item individually. Correctly applying the order of operations ensures accurate financial calculations.
