(34) = ??

We move right to left.

Step - 1 As per the rule, unit place digit is squared

i.e Square of 4 = 4 x 4 = 16 (1 of 16 will be carried over)

Step - 2 Apply the rule “Pair of digits multiplied and doubled” on 4 and 3

i.e 4 x 3 = 12

Double of 12 is 24

1 carried from the previous step gets added to 24, which makes it 25 ( 2 of 25 will be carried to the next step)

Step - 3 Apply the rule “single digit is squared ” on tens’s place digit i.e. 3 in this case.

i.e 3 x 3 = 9

2 carried from the previous step gets added to 9, which makes it 11

Thus the answer is 1156
