Answer 1

128*2+172*2= 2(128+172)=2*300=600
560:(201-197)*0=0
189:9+711:9=(189+711):9=900:9=100 
195*5-5*195=0

How to Quickly Find the Values of Expressions from Homework

If Tommy wants to quickly find the values of the expressions from his homework, he can follow these steps:

1. Break down the expressions into smaller parts to simplify the calculations. 2. Use the order of operations (PEMDAS/BODMAS) to solve the expressions in the correct order: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). 3. Use a calculator or a calculator app to perform the calculations accurately and efficiently.

Now let's apply these steps to the given expressions from Tommy's homework:

1. 128 * 2: - Multiply 128 by 2: 128 * 2 = 256.

2. 172 * 2: - Multiply 172 by 2: 172 * 2 = 344.

3. 560 : (201 - 197) * 0: - Subtract 197 from 201: 201 - 197 = 4. - Divide 560 by 4: 560 / 4 = 140. - Multiply 140 by 0: 140 * 0 = 0.

4. 189 : 9: - Divide 189 by 9: 189 / 9 = 21.

5. 711 : 9: - Divide 711 by 9: 711 / 9 = 79.

6. 195 * 5 - 5 * 195: - Multiply 195 by 5: 195 * 5 = 975. - Multiply 5 by 195: 5 * 195 = 975. - Subtract the second result from the first: 975 - 975 = 0.

7. 85 * 7: - Multiply 85 by 7: 85 * 7 = 595.

8. 85 * 3: - Multiply 85 by 3: 85 * 3 = 255.

9. 97 + 97 * 9: - Multiply 97 by 9: 97 * 9 = 873. - Add 97 to the result: 97 + 873 = 970.

10. 98 * 4 - 89 * 4: - Multiply 98 by 4: 98 * 4 = 392. - Multiply 89 by 4: 89 * 4 = 356. - Subtract the second result from the first: 392 - 356 = 36.

11. 92 * 9 - 92 * 8: - Multiply 92 by 9: 92 * 9 = 828. - Multiply 92 by 8: 92 * 8 = 736. - Subtract the second result from the first: 828 - 736 = 92.

12. 728 - 69 - 69: - Subtract 69 from 728: 728 - 69 = 659. - Subtract 69 from the result: 659 - 69 = 590.

Therefore, the values of the expressions from Tommy's homework are as follows:

1. 128 * 2 = 256 2. 172 * 2 = 344 3. 560 : (201 - 197) * 0 = 0 4. 189 : 9 = 21 5. 711 : 9 = 79 6. 195 * 5 - 5 * 195 = 0 7. 85 * 7 = 595 8. 85 * 3 = 255 9. 97 + 97 * 9 = 970 10. 98 * 4 - 89 * 4 = 36 11. 92 * 9 - 92 * 8 = 92 12. 728 - 69 - 69 = 590

Please note that these calculations are based on the given expressions, and the values may vary depending on the context and the order of operations used.
