Answer 2

Let's break down the calculations step by step:

1. 229 + (-215) + (-315) + (-129) To add positive and negative numbers, you can simply combine their magnitudes and use the sign of the larger number. In this case, we have three negative numbers and one positive number. So, we add the absolute values of the numbers and use the negative sign since there are more negative numbers. = -215 - 315 - 129 + 229 = -430 - 129 + 229 = -559 + 229 = -330

2. -349 + (-210) + 160 + (-352) Here, we have two negative numbers and two positive numbers. We add the absolute values of the numbers and use the sign of the larger number, which is negative. = -349 - 210 + 160 - 352 = -559 + 160 - 352 = -399 - 352 = -751

3. (-17) * 32 To multiply a negative number by a positive number, we multiply the magnitudes and assign the result a negative sign. = -17 * 32 = -544

4. (-81) / (-9) When dividing two negative numbers, the result is positive. We divide the magnitudes and assign the result a positive sign. = 81 / 9 = 9

5. (-192) * (-32) Multiplying two negative numbers results in a positive number. We multiply the magnitudes and assign the result a positive sign. = 192 * 32 = 6144

6. 21 * (-43) Multiplying a positive number by a negative number results in a negative number. We multiply the magnitudes and assign the result a negative sign. = 21 * 43 = 903

So, the answers to the given expressions are: -330, -751, -544, 9, 6144, -903.
