Louis Braille’ (1809-1852), “Procedure for Writing Words, Music, and Plainsong in Dots”, 1829 was the topic of an earlier blog post.
Here I present: Fred Gissoni, “Using the Cranmer Abacus’ for the Blind”, 1964. PART THREE (III).
INTRODUCTION.
Louis Braille’ in 1829 created the Braille symbol system of dots as written language. Numerals (123456789’0) of the Braille number system are shown BELOW.
Numerosity is capacity of number, intrinsic and inherently human. Hands of humans allow for counting in countless ways. Five (5) and twelve (12) are shown BENEATH as two common countings. The term “dyscalculia” (countless) is often used synonymously with “dyslexia” (readless) but are different disorders.
