### Example 1: 42 X 11

Step 1: Here the unit’s place digit is 2 which we will enter as it is i.e 2
Step 2: Here the ten’s place digit is 4, so we input it as follows leaving a blank between the unit’s place digit and the ten’s place digit for the middle digit.
4_2
Step 3: Now, By adding unit’s place digit and ten’s place digit (4+2=6)we get the middle digit as 6 which we shall enter in the blank as follows.
462
Ans : 42×11=462
