Answer 2

To solve the given expressions:

1. 2 * 100 + 5 - 10 + 7

We can start by performing the multiplication operation first: 2 * 100 = 200

Then, we add the remaining numbers: 200 + 5 - 10 + 7 = 202 - 10 + 7

Next, we perform the subtraction operations: 202 - 10 = 192

Finally, we add the remaining number: 192 + 7 = 199

Therefore, the result of the expression 2 * 100 + 5 - 10 + 7 is 199.

2. 9100 + 7.10 + 5

First, we perform the multiplication operation: 7.10 = 70

Then, we add the remaining numbers: 9100 + 70 + 5 = 9170 + 5

Finally, we perform the addition operation: 9170 + 5 = 9175

Therefore, the result of the expression 9100 + 7.10 + 5 is 9175.

3. 3 * 1000 + 6 * 100 + 8

We start by performing the multiplications: 3 * 1000 = 3000 6 * 100 = 600

Then, we add the results of the multiplications and the remaining number: 3000 + 600 + 8 = 3600 + 8

Finally, we perform the addition operation: 3600 + 8 = 3608

Therefore, the result of the expression 3 * 1000 + 6 * 100 + 8 is 3608.
