Section \( 5.1: \) Addition and Subtraction of Integers Score: \( 18.08 / 22 \) Answered: \( 17 / 22 \) Question 21 Which of the following statements are TRUE? Select ALL true statements. (HINT: try different numb check each statement.) Zero minus a number is the same as a number minus zero. Subtracting a positive number from a negative number always gives you a negative number. The difference of a number and its opposite gives you zero. A positive number minus a negative number is always a positive number. subtracting a - b is the same as adding a + (-b). Submit Question
