With the help of number names from one to ten, we can write or read highervalue numbers in words. To write a number in words in English we will use the place values (ones, tens, hundreds, thousands, lakhs, crores, and so on...) of each digit in the number.

Numbers in Words in International System
The international system has different place value names for a certain position of a digit in a number. For example, the number 1,000,000 is read as 1 million in words in the international system, whereas, it is read as 10 lakhs in the Indian place value system. In the international system, different periods are formed to read and write large numbers easily. As per the International numeration system, the comma is placed in a number after the hundreds place and then placed after every three digits. The place values in the international system are Ones, Tens, Hundreds, Thousands, Ten Thousand, Hundred Thousands, Millions, and so on.
 1 million = 1000 thousands
 1 billion = 1000 millions
For example, the number 7,456,123 is written or read in words as seven million four hundred fiftysix thousand one hundred twentythree in the international number system.
Rules to Write Number Names
Certain rules can be followed while writing the numbers in words. These rules are listed below in detail.
Rule 1: Understanding the place value system: The position of a number plays a very crucial role in writing a number in words. Let us understand how to differentiate between the place values based on the position of 1:
 1 = ones place
 10 = tens place
 100 = hundreds place
 1000 = thousandths place
Rule 2: For numbers between 120 we can directly refer to the number names 1 to 20 chart to write their spellings. For example, the number name of 7 is seven, the number name of 15 is fifteen, and so on. After number 20 a generic series or a pattern is followed.
Rule 3: The number names for multiples of 100 can be simply written by adding the word “hundred” after the initial word. For example, the number name of 400 is four hundred, the number name for 500 is five hundred, and so on.
Rule 4: To write the number names of more than 2 digit numbers, we write the number in its expanded form. For example, 112 = 100 + 12, and 112 in words is written as one hundred twelve. The expanded form of 153 = 100 + 50 + 3 and 153 in words is written as One hundred fiftythree.
