Many times, players may have to walk or ride a minecart thousands of blocks in order to get from one place to another. However, the Nether can be used as a much quicker travel, because coordinates in the Nether are $1/8$ the number they are in the Overworld. This means that the distance traveled in the Nether, that would be traveled in the Overworld, is 8 times as short as it would be if it were to be traveled in the Overworld.

Introduction
Usually when people have outposts in other biomes, they travel there via minecart.

But by using maths, you can get there via a nether portal!

Materials
You will need the following materials:


 * 10 obsidian (or 14 if you want to fill in the corners with obsidian)
 * A flint and steel, fire charge, or anything that can set the inside of the nether portal on fire

And These Facts
X- Increases east, decreases west.

Y- Increases by height, decreases by depth.

Z- Increases south, decreases north.

You can relocate portals in the nether using a little math.

Steps
1. Nether portal. If you don't have one, make one.

2. Find your desired location you want to travel to.

3. Note the coordinates of the area, then divide the X and Z values by 8 or by 3. You can ignore the Y value.

4. Go through your portal & head to those divided coordinates. Try to place yourself at about the same elevation, then make your portal. You should come out about where you were previously.

Note: This works because one block in the nether is equal to eight blocks in the over world. For example, to travel 800 blocks in the over world, you would only need to travel 100 blocks in the nether.
