|7|+|−2| = ____ Note: This problem shows the number -2 within an absolute value sign, not the number -21. A. 9 B. 5 C. 0 D. 14 - A. 9 9 is the correct answer because the brackets around the numbers mean you are adding the absolute value of those numbers. The absolute value of a number is always positive, so: The absolute value of 7 is 7.The absolute value of -2 is 2.Therefore, the problem becomes: 7 + 2 = 9. Note: You will not do anything to signs outside the absolute value bra...
