Missing Number in Addition
The basic concept of finding the missing number in addition sum of one-digit number. These give us support and idea about the basic addition facts, as well as help us to understand the addition's relationship to subtraction. It also assists as an introduction to learning algebra (as the missing number could be represented by a variable or a letter). While solving the addition problems children will complete the missing addend to find the correct calculation. Now we will learn how to find missing number in addition.
What is the missing number in these addition sums?
(i) 3 + ? = 8
Follow the procedure to find the missing addend. The question given is ‘3 and how many more make 8?’ The answer is 5.
Therefore, when the number is put in the place of the question mark (?), the sum is written as 3 + 5 = 8.
(ii) ? + 2 = 6
To find the missing addend we read the question given as ‘how many more and 2 make 6?’ The answer is 4.
Therefore, when the number is put in the place of the question mark (?), the sum is written as 4 + 2 = 6.
(iii) 5 + ? = 9
To find the missing addend we read the question given as ‘5 and how many more make 9?’ The answer is 4.
Therefore, when the number is put in the place of the question mark (?), the sum is written as 5 + 4 = 9.
(iv) ? + 6 = 7
To find the missing addend we read the question given as ‘how many more and 6 make 7?’ The answer is 1.
Therefore, when the number is put in the place of the question mark (?), the sum is written as 1 + 6 = 7.
