Answer: 200
Step-by-step explanation: Absolute value means distance from zero on a number line. So for the absolute value of -200, we know that -200 is 200 units from zero on a number. So the absolute value of -200 is 200.
Another way of thinking about absolute value is that no matter what number you have inside the absolute value, the result will always be positive except for the absolute value of zero which is zero.
