You must have listened to million, billion, trillion in math, financial aspects, science, and at a lot more places in everyday life. Few common questions arise in our minds when these words come together. Then, at that time, how would you memorize the number of zeros in those large numbers? Are you still counting the number of zeros in thousand, million, billion, trillion by rote? What comes beyond a trillion? What is the best way to conceptualize zeroes in a million, billion, trillion? Here is the quickest decode of the problem.
Introduction to International Numeral System:
Before moving ahead, we need to know traditional counting over numerical counting systems. In ancient times counting was considered as a physical object like stones, rocks, and sticks. For time being numbers introduced to human society. Eventually, we started counting using numerical notations.
A numeral system is the system of communication of numbers (read, write) with numerical notations for addressing quantities of a given set. The number in the numeral representation is called its value.
Zero is the important number in the Numeral system called a “placeholder”. Adding one zero next to the number results in a multiplication of 10, which means ten-time higher than the defined value.
Additionally, we will overlook on a Long & short scale.
The long & short scales are two large numbers having a different meanings. The long scale is termed as a power of one million (1,000,000) & short-scale based on a power of a thousand (1000). In Europe (French-Speaking, Spanish-Speaking) long scale is widely used. However, In English & Arabic-speaking regions short scale is widely used. During 19-20th centuries, the UK largely used long scale, whereas the US largely used short scale. Eventually, the UK adopted short scale for official purposes.
Long Scale: “billion” (1012) means a million million,
Short scale: “billion” (109) means a thousand million,

How to differentiate million, billion, trillion?
Million: Multiplication of thousand with thousand (1000×1000) or (106),
(Number of zeros: 6)
Billion: Multiplication of thousand with million (1000×1,000,000) or (109),
(Number of zeros: 9)
Trillion: Multiplication of thousand with Billion (1000×1,000,000,000) or (1012),
(Number of zeros: 12)
Zeros are divided into sets of three. Three sets of zeros are separated by a comma separator from the left to right for better understanding & readability.
The ideal way remembers the number of zeros:
Now you shouldn’t be worried about how to remember zeros in million, billion, trillion & so on and so forth. Stop memorizing by rote. The rule is very simple.
Million: Million consists of 2 sets of 3 zeros (000,000) else can say six zeros.
Billion: Billion consists of 3 sets of 3 zeros (000,000,000) else can say nine zeros.
Trillion: Trillion consists of 4 sets of 3 zeros (000,000,000,000) else twelve zeros.
What is the largest number in the universe?
The largest number in the universe is googol. Googol is a combination of 100 zeros. Numerically written as 10100. Are you shocked after reading a hundred zeros? Wait… Another largest number persists beyond googol. The name is googolplex. Numerically it is written as 1010(100). Googolplex is the largest existing number in the universe. However, human is hardly in use with such a gigantic number.
Googol:
10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
Common examples of million, billion, trillion on everyday life:
Nowadays the best way to relate to million is the population of India is 1.39 billion or 1393 million. The population of US 332million or 0.33 billion.
Like that trillion can be related to GDP (Gross domestic products) of the country. The USA has an economy of 19 trillion, China has a GDP of 12 trillion.
