What are Number Names?
A number is an arithmetic value that can be written in words or symbols and is used to count things and perform calculations.
How to Write the Names of Numbers in Words?
To write number names from 1 to 20, there are a few rules that need to be followed. Firstly, we should write the given number in the expanded form, such as the number 17 = 10 +7.
Secondly, we will write and combine the respective names of all the addends. For example, 10 + 7 = Seventeen.
Here is how to identify the first 4 place values based on the position of 1:
1 = the ones place
10 = the tens place
100 = the hundreds place
1000 = the thousands place
Now, let’s have a look at the number names from 1 to 20 in the next section.
Number Names from 1 to 20
The following chart shows us the names of the numbers from 1 to 20.
Solved Examples
Example 1:
Find out the value of 13 + 5 – (2 + 4) and write the result in words.
Solution:
13 + 5 – (2 + 4)
Simplify the given equation
= 13 + 5 – (2 + 4) [Apply PEMDAS]
= 13 + 5 – (6) [Simplify]
= 18 – (6)
= 12
12 can be written as:
10 + 2 = Ten + two = Twelve
Therefore, 13 + 5 – (2 + 4) = Twelve.
Example 2:
What is the value of seventeen minus eleven?
Solution:
The given equation is in the form of words, that is seventeen minus eleven.
In numerical format, seventeen can be written as 17 and eleven as 11.
Then,
\(\Rightarrow \) 17 – 11 = 6 (Six)
Therefore, the value of seventeen minus eleven is six.
Example 3:
James has 5 candies and his friend Adam gave him 8 more. What is the total number of candies with James? State the result in words.
Solution:
Number of candies James has = 5
Number of candies that Adam has given to James = 8
Then,
The total number of candies with James are = 5 + 8
= 13
Thus, 13 is written as thirteen in words.
Therefore, James has thirteen candies in total.
Numbers are arithmetic values that are used to represent a quantity or amount.
