 ==Visual Numerals in Turtle Art==
-It should be obvious that having a Turtle write most of these numerals is fairly simple to do. We can create TA stacks for each digit in one of these systems, and display whatever sort of arithmetic we want. For example,
+It should be obvious that we can have a Turtle write out arithmetic examples by drawing these numerals. Or we can tell the Turtle to display these characters directly as text.

-We can also put these numerals on Turtle Art tiles as text. In the following illustration, each Hieroglyphic heqat measure numeral is used as a variable name with value the number it represents.
+We can also put these numerals on Turtle Art boxes. In the following illustration, each Hieroglyphic heqat measure numeral is used as a variable name with the number it represents assigned as its value. As a curiosity, the box with a blank name contains the value 0. It works fine in arithmetic.
