Learning to hear and say numbers in any language is a very important for day-to-day communication in that language. To learn numbers in English, you can break them down into sets and categories that follow similar rules, thereby making them easier to remember.
Start with 1 through 10
The numbers 1 (one) through 10 (ten) are the basic building blocks of the number system in most languages. By learning 1 through 10, you will have been introduced to every symbol used in the English counting system and the name for when that symbol appears in the "ones" place, which is the right-most digit of a whole number. Learn 1 through 10 before continuing.
Learn the irregular numbers
In some languages, the numbers 11 through 19 do not follow the same rules as many of the other counting numbers. In English 11 (eleven) and 12 (twelve) are the most irregular, but the rest of the numbers between 10 and 20 follow a pattern. They take the ones-digit's name, or part of the name, and add "teen." This might make it easier to remember numbers like 13 (thirteen), 14 (fourteen), 15 (fifteen) and so on.
Count by tens to 100
After 19, all two-digit numbers follow the same formula. Most or all of these numbers include the tens-digit name and the suffix "ty," which is followed by the ones-digit name unless that digit is a zero. For example, 20 is written as twenty, 21 is twenty-one, 30 is thirty, 45 is forty-five and 89 is eighty-nine.
Piece together 3-digit numbers
Three-digit numbers read from left to right, starting with the hundreds digit and then reading the next two digits as they would be read without the hundreds digit. Hundreds digits are always said with that symbol's name followed by the word "hundred." For example, 100 is written as one hundred, 300 is written as three hundred and 425 is written as four hundred twenty-five.
