Answer: 4
1) Let's say that the starting point on a numberline is 2 because your equation started with a number 2.
--> We know from our study of Algebra that there is a one-to-one correspondence between the set of real numbers and the infinite number of points on a horizontal straight line) Now that the person is standing at zero, the rules are that any movement by the individual to the right is in the positive (+) direction and that any movement to the left is in the negative (‒) direction.
2) Let's say that the individual moves from zero to the right 2 units to the point or to the position on the real number line that corresponds to and is labeled positive 2; therefore, we see that positive 2 has an absolute value of 2.
--> Remember, an absolute value is a distance between the number and 0 on a number line.
3) The individual decides to move to the right 2 additional units, an increase in the absolute value of 2, from the position of positive 2 to the point or position on the real number line that corresponds to and is labeled positive 4; therefore, the total distance of the individual from zero is now 4 units to the right (an absolute value of 4)
So in conclusion, the answer is 4.
