This was created specifically for teachers and parents to help display visual representations of word problems. Each letter correlates to a value and the upper and lowercase share the same width. For example, if you want to display 1 + 9 = 10, the A represents the 1 and the lowercase a has the 1 width bracket. The I represents the 9 bar and the lowercase 9 represents the 9 width bracket. To show the full width, you would use the 10 which represented by the J. A-1, B-2, C-3, etc...
