5 + 3 equals 8. This is a basic addition problem involving positive integers. The other options do not result from correctly adding 5 and 3.

-4 + 2 gives -2 because the positive number does not fully cancel out the negative value. The sum remains negative as 4 is greater than 2. Thus, -2 is the correct answer.

Subtracting 10 from 7 results in -3 because you are effectively adding a negative 10. This correct application of subtraction leads directly to -3. The other options represent common arithmetic mistakes.

When subtracting 3 from -6, you move further into the negatives, resulting in -9. The process shows the additive effect of negative numbers. The other options do not accurately reflect this calculation.

Adding two negative numbers results in a sum that is even more negative, so -8 plus -2 equals -10. This follows the rule that the absolute values add together and the sign remains negative. The other choices do not follow this arithmetic rule.

First, adding 12 and -7 yields 5, and then adding 3 gives a final sum of 8. This problem reinforces combining positive and negative integers in sequence. The other options result from computational errors.

Subtracting a negative number becomes addition; hence, -15 - (-5) gives -10, and adding 2 results in -8. This step-by-step calculation demonstrates proper handling of negative signs. The incorrect choices arise from misapplying these rules.

Adding -3 and -4 gives -7, and subtracting 2 results in -9, demonstrating the cumulative effect of negative numbers. The process underlines the importance of carefully combining negative values. Other options do not correctly follow the subtraction steps.

Subtracting 15 from 20 produces 5, and adding -8 results in -3. This problem tests the understanding of combining subtraction with negative numbers. The other alternatives are the outcomes of common calculation mistakes.

Adding -6 and -4 results in -10, and then adding 12 produces a final value of 2. This demonstrates how positive numbers can offset negative sums. The incorrect options reflect common miscalculations in integer operations.

First, (-10) + (-5) equals -15, and adding 15 cancels out the negative sum to achieve 0. This cancellation principle is fundamental in integer arithmetic. The other choices arise from misinterpreting the relationship between positive and negative totals.

Subtracting a negative number is equivalent to adding the positive; hence, 8 + (-3) gives 5, and then adding 7 results in 12. This reinforces the concept of double negatives. The remaining options result from failing to properly convert the subtraction of a negative.

Converting -(-4) to +4, the calculation becomes -9 + 4 which is -5, and subtracting 3 results in -8. This problem highlights the importance of handling double negatives correctly. The other options do not follow the proper steps.

The sum is computed step-by-step: (-2 + 4) equals 2, then 2 - 6 equals -4, and finally -4 + 8 equals 4. The procedure demonstrates sequential addition and subtraction with integers. The other answers stem from misordering the operations.

Subtracting a negative is equivalent to adding its positive, so 5 - (-8) becomes 5 + 8, which equals 13. This underscores a key property of integer operations regarding subtraction of negatives. The alternative options do not correctly apply this rule.

Starting with a debt of -15, receiving 9 dollars increases her balance to -6, and paying off 4 dollars reduces it further to -10. This sequential calculation correctly applies the rules for adding and subtracting integers. The other options do not follow the correct order of operations.

Starting at -200, ascending 45 meters brings the position to -155, and then descending an additional 60 meters results in -215. This problem requires applying both addition and subtraction with negative numbers to track changes in depth. The distractors stem from common miscalculations in interpreting the changes.

The evening drop of 5°C takes the temperature from -7°C to -12°C, and the subsequent rise of 3°C results in -9°C. This sequential adjustment of temperature illustrates proper handling of integer operations with negatives. Other options result from incorrectly applying the temperature changes.

First, calculate the bracket: 3 - (-4) becomes 3 + 4, which equals 7. Then, the expression simplifies to -2 - 7 - 6, equaling -15. The other choices are incorrect due to improper handling of the negative sign within the brackets.

Starting from 0, losing 4 points yields -4, gaining 7 points raises the total to 3, and then losing 10 points results in a final score of -7. This problem showcases sequential integer operations in a real-world context. The other options arise from miscalculating one or more steps in the process.
