Writing the symbol for the number being represented can be a difficult task. It requires knowledge of basic mathematical symbols and an understanding of how numbers are represented in different forms. For example, when given a number on an abacus, one must know how to read it and then write its code. Likewise, when given a number on a house plate, one must be able to interpret the number and write its code. In addition, when asked to compare fractions and mixed numbers on a number line, one must understand how these numbers are represented by their respective symbols. Understanding the numbers represented is the first step towards mastering mathematics!
