How to Recognize the Sounds of a Number

One way to practice internalizing the sounds and images is just taking something that you enjoy like an article and just converting them into the digits. You can just take a string of numbers and just practice turning them into their different sounds. That's known as the major system. And I will explain how to exactly use it. But before I do that, any any questions on this part? We have a question. Is there a reason why some letters are not present or associated with a number because they appear less than the English language or not? It's commonly used. So I don't know exactly the reason.
