The answer is:

STRING

By doing:

HINT 2: Adding the same squares together and assigning alphabets in the A1Z26 format we get "NOTHING IS WRONG"

Then:

Writing down the second clue we get 00X0X0X0X0X0X0, which has the same number of characters as NOTHINGISWRONG

Hence:

Using Hint 3, classifying (dividing into 2) the letters from NOTHINGISWRONG using the positions of 0s and Xs, we get NOHNIWOG and TIGSRN

Finally,

The anagram of the second statement TIGSRN is STRING

The answer is:

STRING

By doing:

HINT 2: Adding the same squares together and assigning alphabets in the A1Z26 format we get "NOTHING IS WRONG"

Then:

Writing down the second clue we get 00X0X0X0X0X0X0, which has the same number of characters as NOTHINGISWRONG

Hence:

Using Hint 3, classifying (dividing into 2) the letters from NOTHINGISWRONG using the positions of 0s and Xs, we get NOHNIWOG and TIGSRN. The first word is ignored because they're all zeros as per Clue 2.

Finally,

An anagram of the second word TIGSRN is STRING
