Abstract

Visual impairment and blindness have a significant effect on the socioeconomic development of people and society. The current state of blindness worldwide is 0.7% with a minimum of 7 million individuals are becoming blind annually and increasing by 1-2 million each year. About 90% of the world’s blind and visually impaired (BVI) live in developing countries, making their education very difficult. Traditionally, Mathematics has been inaccessible to BVI because its content is rich with visually presented concepts and information.
