Absolute value

You'll find absolute value absolutely straightforward--it is just the "distance from zero". If you have a positive number, it is its own absolute value. If you have a negative number, just make it positive to get the absolute value. As you see as you develop mathematically, this idea will eventually extended to more contexts and dimensions, so super important that you understand this core concept now.

Let's mix a little algebra into our discussion of absolute value. What if we are looking for the |x|? If we know what x equals, we can do it. Follow along.

Comparing absolute values
