Answer:
According to BODMAS rule, first we will multiply 11 by 11 which= 121 which would be further subtracted by 11 [there is a rule which says that we have to solve from left to right if there is addition, subtraction or multiplication, division and here we have 11-121+11 and hence we would solve 11-121 first.. ] So, we would have -110 and then finally add to 11 which would give -99
