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.

Choice B and D are both correct.

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).
