Question

Which of the following are true statements about the expression 6 - (-6) Choose all answers that apply: (Choice A) The expression describes the number that is 6 to the left of 6 on the number line. (Choice B) The expression describes the number that is 6 to the right of 6 on the number line. (Choice C) C The expression equals 0. (Choice D) D The expression equals 12.

Answer 1

Answer: Choice B and D are both correct.

Step-by-step explanation:

The expression has two adjacent negative signs in the middle. The two negative signs are to be multiplied, which then produces one positive sign.

Choice B is therefore correct because the expression becomes 6+6 which is 6 to the right of the number line where the numbers are increasing.

Choice D is also equally correct because the addition of 6 to 6 equals 12(6+6 = 12).
