Match the mathematical statements with the statements written in English. All of these statements are true.

Draggable item		Corresponding Item
\|-15\| > \|-12\|		The distance between -12 and 0 on the number line is greater than -15.
\|-12\| > -15		The number -15 is less than the number -12.
\|-12\| = 12		The number -15 is further away from 0 than the number -12 on the number line.
\|12\| = \|-12\|		The number -12 is a distance of 12 units away from 0 on the number line.
12 > -12		The number 12 is greater than the number -12.
-15 < -12		The numbers 12 and -12 are the same distance away from 0 on the number line.
