What is distance between ( -12 ) and ( 6 )
Answer and explanation
Correct answer: 18
On a number line, the distance between two numbers is the absolute value of their difference. Thus, \(\lvert 6-(-12)\rvert=\lvert 18\rvert=18\). Therefore, 18 is correct. The value 12 is only the absolute value of -12, not the distance between the two numbers. Exam tip: always take the absolute value of the difference when finding distance.
