Explain how you would use a number line to find the absolute value of –12.

This is kind of hard to explain, but I'm going to try. Feel free to comment questions if what I'm going to say doesn't make sense.

Absolute Value
∞ # of spaces away from zero
∞ how far away a number is from zero

1). Draw a number line.
2). Label it from -12 to 0.
3). Count on the number line from -12 to 0 and see how many units to the right you have to go to reach zero. The answer is 12, so that is the absolute value.
 |-12| = 12

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
