# Learn Braille with DOTS

To understand Braille, we need to take a look at how a Braille cell is structured. A Braille cell is made up of six dots, two columns of three dots. The dots are numbered from top to bottom, left to right (refer to the image below). Each combination of dots represents a number on the die face. Additionally, there is a ridged line on each die face which serves as the bottom of the Braille cell to provide an orientation points for the dots. If you look at a six-sided, the pips on the number six looks just like a Braille cell.

In Braille, the numbers 1-9, followed by the number 0, are made using the letters A-J respectively. To distinguish numbers from letters, Braille utilizes a number symbol in the cell proceeding the letter. To create numbers larger than one digit, a number symbol is followed by a series of cells with letters, one per cell. For example, the number 20 would use 3 cells: A number symbol, the letter B (represents 2), and the letter J (represents 0). To simplify the numbers on the dice to one cell, each die face has a ridged line that designates the bottom of the cell as a point of orientation for the dots. The Letters A-J represent the numbers 1-10 respectively, and the letters K-T represent the numbers 11-20 respectively. Below is a quick reference chart to help you learn the letters, and the numbers they represent!
