Question: 1 / 400

What does the acronym KCC stand for in the context of subtracting integers?

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.
