Answer 1

The expression 6 + (-6) equals 0.

Step-by-step explanation:

The statement that is true about the expression 6 + (-6) is:

C. The expression equals 0.

To add a positive number and a negative number, we subtract the absolute value of the negative number from the absolute value of the positive number, and then assign the sign of the larger number to the answer.
