Write the letters D, M, and V in the triangle in the order that you reach each section as you go from left to right. The diagram below will show you how this is done.

To find the formula for "** Density**," cover up the "

This leaves the the "**M**" over the "**V**," giving you the formula "**M/V**." Therefore, the fomula is D=M/V

To find the formula for "** Volume**," cover up the "

This leaves the the "**M**" over the "**D**," giving you the formula "**M/D**." Therefore, the formula is V=M/D.

To find the formula for "** Mass**," cover up the "

This leaves the the "**D**" over the "**V**," giving you the formula "**D x V**." Therefore, the formula is M=D x V.

To simplify this, I would change the type of isoline to a specific one that makes it easier to remember. My suggestion is to change the isolines to contour lines, because in the case of contour lines, the field is elevation, which provides an easier trick for remembering the formula.

The formula now goes from "**G=F/D**," where **G=Gradient**, **F=Field**, and **D=Distance** to "**The GED Triangle**. The field in contour lines is
