How do I learn to read Braille?

Start by learning the decade system: the first 10 letters (A-J) use only the top four dots. The next 10 letters (K-T) add dot 3 to the same patterns. Letters U-Z add dots 3 and 6. Practice with simple words first, then progress to sentences with capital and number indicators.

Why was W added differently in Braille?

Louis Braille designed his system for French, which did not use the letter W at the time. When W was later needed for other languages (particularly English), it received a unique pattern (dots 2,4,5,6) that does not follow the decade system used by the other letters.
