Plot the number on the number line; count off the distance from -12 to zero.
-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 There is a distance of 12.
Distance from (0, 0) to (5, 12) using distance formula is 13
The difference between two numbers is determined by subtracting the smaller number from the larger number. For example the difference between 12 and 9 is: 12-9=3. For negative integers, you will see that the difference is the total distance. For example, the difference between (-12) and 9 is 9-(-12) when you simplify by eliminating the double sign, the two minus signs become one plus sign: 9+12=21. More simply put, you will have to travel 12 to get from (-12) to zero, then another 9 to travel the total distance (difference) of 21.

26 here is why: on the number line the distance between 14 and 8 is 6, so we need a number whose distance between 14 and that number is 12.. so 12+14=26 and that works
Plot the number on the number line; count off the distance from -12 to zero.
the number between 11 and 12 is obvious. it is 11 and a half
-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 There is a distance of 12.

The straight line distance between 9 miles west and 12 miles south is the hypotenuse of a right triangle with sides 9 and 12. Using the Pythagorean theorem, the distance would be √(9^2 + 12^2) = √(81 + 144) = √225 = 15 miles.
13 if you refer to a number line. If you subract you will get -1-12 = -13
It is 5 because 5+7 = 12 and 5-7 = -2
Irrational numbers can be represented on a number line. For example, to graph the square root of two, draw a line of 1 unit (1 unit = the distance between the points of two whole numbers) from -1 which is perpendicular to the number line. Then, using a compass, place the pointy end on 0, the pencil tip on the end of the drawn line that is not touching the number line and drawing an arc so that it hits the number line on the positive side. Draw a point at where the arc meets the number line. That point is the square root of 2. This works because of Pythagoras theorem (a2+b2=c2, 12+12=22).
