주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Adding Integers

Adding integers involves combining their values on the number line. When both integers have the same sign, add their absolute values and keep the common sign. For example, -6 + (-13) means adding two negative numbers.

Understanding Negative Numbers

Negative numbers are values less than zero, represented with a minus sign. They lie to the left of zero on the number line. Adding negative numbers results in a more negative value, moving further left.

Sum and Difference of Integers

The sum of integers is the result of their addition, while the difference is the result of subtraction. For sums involving negative numbers, consider their signs carefully to determine the correct result.
