There are many different ways to solve this problem. The simplest way is to count how many numbers. You can also use algebra: 2=-5+X 2+5=X X=7. You can subtract -5 from 2: 2-(-5)=2+5=7. You can also add the absolute Values: |-5|+|2|=5+2=7. I am sure there are many others, but these methods confirm the answer to be 7. Hope that helps.

Just subtract the lowest number from the greatest number. For example, the distance between 3 and 8, is 8 - 3 = 5 units, the distance between -2 and 3, is 3 - (-2) = 3 + 2 = 5 units, the distance between -4 and -2, is -2 - (-4) = -2 + 4 = 2 units.
A LINE CONSISTS OF THE LINEAR DISTANCE BETWEEN 2 POINTS.
The absolute value of a number is the distance the number is away from 0. For example, on the number line 2 is 2 units from 0 So |2|=2. But, -2 is also 2units away from 0 on the number line, so |-2|=2 as well. In general for any real number x , |x| is the distance from x to 0 on the number line. That helps us see why if x is a negative number, the distance from zero must still be positive. So for x<0, |x| is -x. For example, if x is -2, the absolute value is -(-2) which is positive 2. In general is a and b are real numbers |a-b|=|b-a| and both are the distance between a and b. Now let a =0 and we have |-b|=|b|

Infinite. !!!! The number line extends from negative infinioty ..... -3,-2,-1,0,1,2,3, ... positive infinity .

The shortest distance between 2 parallel lines is a perpendicular drawn between 2 parallel lines the diagram shows it clearly 1 parallel line ------------------------------------|-------------------------------------------------------------------- | | | the vertical line is the shortest distance | | ------------------------------------|------------------------------------------------------------------- 2nd parallel line
The number directly in the middle of 2 and -3 on the number line is -0.5.
Measurement always deals with a distance of a line or a distance between to objects, distance between 2 points, and so on.
Straight line, between Teheran and Bucharest the distance is ca. 2 350 km.
