As we can see the pattern, which is
The two number which are getting multiplied, first of all the individual digits of the numbers gets added then they are multiplied, for e.g. in
11*11 first number 11 is added individually i.e. 1+1=2 and then the second 11 i.e. 1+1=2 and now 2*2 is applied i.e. 4
Similarly for 33*33=6
We, get 3+3=6 and then the second 3+3=6 and now
6*6=36, therefore 33*33=36
So, for 55*55
First 55 gets added individually i.e. 5+5=10
And then the second 55 gets added individually i.e. 5+5=10 and hence,
10*10=100
Therefore,55*55=100
