Final answer:
The process of simplifying expressions involves performing the appropriate arithmetic operations, such as multiplication and subtraction, to obtain the final results. The calculations were carried out step by step for each expression.
Step-by-step explanation:
The question requires simplifying expressions by performing multiplication and subtraction on numbers. We will do this step by step.
- For (4 • 10) (5 - 100), you first multiply 4 by 10 to get 40, and then multiply 5 by -100 to get -500. The result is 40(-500) which equals -20,000.
- (2 • 100) (7 • 10) is simplified by multiplying 2 by 100 to get 200, and then multiplying 7 by 10 to get 70. The final result is 200(70), which equals 14,000.
- In (6 • 100) - (1 • 10), you multiply 6 by 100 to get 600 and 1 by 10 to get 10. Subtracting the two gives 600 - 10, which is 590.
- (9 • 1,000) (4 • 10) is simplified by multiplying 9 by 1,000 to get 9,000 and 4 by 10 to get 40. The final result is 9,000(40), which equals 360,000.
- To find (3 • 1,000) - (2 • 100), multiply 3 by 1,000 to obtain 3,000 and 2 by 100 to obtain 200. Subtracting the two results in 3,000 - 200, which equals 2,800.
- Lastly, (2 • 10) (7 • 100) requires multiplying 2 by 10 to get 20 and 7 by 100 to get 700. The multiplication of these two results in 20(700), equating to 14,000.
