Introduction to the Missing Numbers
Do you know the importance of missing numbers in our life? If not, then it's okay, as this article will explain everything about the missing number and the missing number worksheet for class 2. Now you must be curious about how to find the missing numbers. After reading this article and solving some missing number worksheets, you will be able to find the missing numbers in addition, and subtraction in various forms like single-digit subtraction, single-digit addition etc along with the benefits of missing number worksheets.
Missing Numbers in Addition
To find the missing digits in addition, follow the steps in the given example:
In addition, to find the missing number, just take the number you have on the left side of the ‘=’ sign and take it to the right side.
Then subtract it from the number that is on the right side. In below case, when we put 8 on the right side, we get
= 10 - 8
= 2
Hence the missing number is 2.
Missing Number in Addition
Missing Single Digit Subtraction Cases
Following the three cases of missing single digit subtraction:
Case 1: If the missing number is the difference then subtract the subtrahend from the minuend. For example:
10 - 3 = __ (Here the blank mark represents the missing number). Now, subtract 3 from the number 10 and note the answer as 7. So the missing number is 7.
The Equation in Which the Difference is Missing
Case 2: If the missing number is the subtrahend then subtract the difference from the minuend. For example:
10 - __ = 7 (Here the blank mark represents the missing number). Now, we will subtract 7 from 10 and obtain the result as 3. Thus, the missing number is 3.
The Equation in Which the Subtrahend is Missing
Case 3: If the missing number is the minuend then add the subtrahend and the difference. For example:
__ - 3 = 7 (Here the blank mark represents the missing number). We wish to add 3 with 7 and get the result as 10. Now, after adding 7 with 3, the missing number is obtained as 10.

Solved Examples
Q 1. Write the missing number in the given sequence.
2, 3, 6, 4, 5, 20, __, 3, 18.
Ans: The missing number is 6. This is because a pattern between the numbers in the given series is determined, as the third digit ‘6’ is the product of the first two digits ‘2’ and ‘3’, and the sixth digit, which is ‘20’ is the product of fourth and fifth digits that is ‘4’ and ‘5’ and the ninth digit ‘18’ is the product of the seventh digit ‘6’ and eighth digit ‘3’
Therefore, the seventh digit should be “6”.
Q 2. Replace _ with the correct digit in __67 + 132 = 399
Ans: Follow the given steps to solve the problem:
Write the given expression: __67 + 132 = 399
Now, take 132 to the right-hand side and subtract from 399, i.e. 399 - 132
So, 399 - 132 = 267
Equate the difference of these numbers to __67 and get the final answer as 2
Thus, the digit at the place of the blank space will be 2.
Practice Problems

Ans. 7.
Q 2. Calculate the missing digit in the addition of 61__0 + 1352 = 7482.
Ans. 3.

Summary
Missing numbers are the numbers that have been missed in a given series of a number or digits with similar differences among them. The method of filling in these missing numbers is finding similar changes or rules between those numbers and filling in the missing terms in the specific series and places. You can also find the missing digits by identifying the pattern of the sequence. Keep practising and solving the missing digits worksheets for class 2.
