Missing Numerals In Addition

To find the missing numeral in Addition we try all the combinations to reach the desired result

For example let us solve the question

The sum 3 can be formed by the following combinations

we know that

1+ 2= 3

2+1 = 3

The figure below shows the combination  1+ 2= 3

There is 1 stick for the first digit 1 and 2 sticks for the second digit 2

Adding the sticks together we get 3 sticks.

Hence the missing number in this case are 1 and 2

Similarly we can show the combination 2+ 1= 3

In that case the missing numbers will be 2 and 1
