The visual character of the alphabetical design that I did for the Yoruba people is actually universal.
Even those who are visually challenged can experience it in a tactile form as braille characters.
The universality of the Yoruba alphabets is not only original and innovative, it makes numbers easier to learn, write, and master for children.
All a child has to do is count what is written one by one, to add or subtract the figures.
For example, in the picture 7 + 8 = 15. In this Arabic design, the writing is not visual. When you view the universal writing of the Yoruba script, simply count the lines, and a child can easily see the seven marks as well as the eight marks to arrive at fifteen.
