The correct answer is: Keep Change Change

In the context of subtracting integers, the acronym KCC stands for "Keep Change Change." This mnemonic is a useful tool to help students remember the steps involved in subtracting integers, especially when a negative integer is involved. When you encounter a subtraction problem, KCC guides you through the process: First, "Keep" the first number as it is; next, "Change" the subtraction sign to an addition sign; and finally, "Change" the second number to its opposite. This effectively transforms the subtraction problem into an addition problem, making it easier to solve. For example, if you have 5 - (-3), you would keep the 5, change the subtraction to addition, and change -3 to +3. This gives you 5 + 3, which equals 8. The other options reflect different variations of the process but do not accurately capture the sequence of actions needed when dealing with integer subtraction.
