First, perform the multiplication: 1000 × 4 = 4000 .
Then, perform the subtraction: 4000 − 5 = 3995 .
The result of the expression is 3995 .
Explanation
Understanding the Problem We are asked to evaluate the expression 1000 × 4 − 5 . This involves multiplication and subtraction. We need to follow the order of operations (PEMDAS/BODMAS), which tells us to perform multiplication before subtraction.
Performing Multiplication First, we perform the multiplication: 1000 × 4 = 4000 .
Performing Subtraction Next, we perform the subtraction: 4000 − 5 = 3995 .
Final Result Therefore, the final result is 3995.
Examples
Understanding order of operations is crucial in many real-life scenarios, such as calculating expenses or determining the outcome of a series of financial transactions. For instance, if you earn $10 per hour and work for 40 hours, but have to pay $5 in taxes, the calculation 10 × 40 − 5 helps you determine your net earnings. This simple arithmetic problem demonstrates how following the correct order of operations ensures accurate financial planning and budgeting.
To evaluate 1000 × 4 − 5 , first multiply to get 4000 , then subtract 5 to find that the result is 3995 .
