AnswerThis is calculating using BODMAS rule.B - BracketO - OfD - DivideM - MultiplicationA - AdditionS - SubtractAny equation should be solved using this order. Firstly expressions inside a bracket should be solved, then Of, then Division and so on.In the equation mentioned, all the red highlighted (underlined) need to be solved first.Firstly we will solve the expression inside ()Then in first line, 9 of 6 = 9*6 = 54 is solvedThen Multiplication is solved, 13*4 =52Then Addition, 54+1 = 55Then Subtraction, 55-52 =3Then in the expression which is in the outer bracket, {8+3-3}. It will also follow same order, Addition first, then subtraction

this problem is solved using BODMAS,BODMAS is an acronym and it stands for Bracket, Of, Division, Multiplication, Addition and Subtraction.
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right. Solving the problem in the wrong order will result in a wrong answer.
Note: The “of” in the BODMAS full form is also called “Order”, which refers to the numbers which involve powers, square roots, etc.
7+[12-{8+3-(9of 6+1-13of4)}]
so here in the first step we look for "B"in BODMAS which stands for brackets, solve brackets inside the brackets we have "of" which is order, which is "O" in BODMAS, so solve the 9*6 and 13*4
which is 9*6= 54, 13*4= 52 in the below step
7+[12-{8+3-(54+1-52)}]
in the next step we look for "D" in BODMAS which is divison present inside brackets, since there are no division, continue with next which is "M" which is solved and not present inside brackets, so next is "A" which is additions is solve it present inside brackets, which is 54+1= 55 , in the below step
7+[12-{8+3-(55-52)}]
in the next order we should look for "S" in BODMAS which is subtraction  present inside brackets, which is 55-52, solve as in next step
7+[12-{8+3-(3)}]
now eliminating the brackets again , the next step7+[12-{8+3-3}]
so again look for BODMAS, since there is no divison and multiplication ,next is "A" which is additions is solve it present inside brackets, which is 8+3=11
7+[12-{11-3}]
so again look for BODMAS, since there is no divison and multiplication and addition in the brackets, so solve for "S" subtraction, which is 11-3=8, as show below
7+[12-8]
now again solve, look for BODMAS, since there is no divison and multiplication and addition in the brackets, so solve for "S" subtraction, which is 12-8=4, as shown below
7+4
 now add 11
so the answer is 11

In Mathematics, 
"of" means to multiply.
We also use the order of operations BODMAS which is used to solve math problems.
Where B stands for Brankets, O - Order/Indices/Powers, D - Divide, M - Multiply, A - Addition and S- Subtraction.This means we solve brackets eg "(), [], {}" first, then we solve the powers/indices eg square root or squared, then divide, then multiply and lastly solve using addition and subtraction from left to right. 
7 + [12 - {8 + 3 - (9 of 6 + 1- 13 x 4)}]

STEP 1:
We solve the numbers or terms in the brackets first. Since there are 3 sets of brackets. We go to the bracket with in the two brackets. So we solve (9 of 6 + 1- 13 x 4) first. Remember, the word "of" means to multiply so change the word to the multiplication sign "x".
(9 of 6 + 1- 13 x 4)
(9 x 6 + 1- 13 x 4)
Since we have our brackets, "B", we move to order, "O". There are NO powers in the problem so we move to division, "D". There are no division signs so we move to multiplication, "M". Where you see the "x" sign, multiply the two numbers that the "x" is between.
(9 x 6 + 1- 13 x 4)}]
=(54 + 1 - 52)

We did the Multiplication, "M" so we move to addition, "A" and subtraction, "S".
NOTE: When there is addition and subtraction only in the brackets or math sum, we solve from left to right.
So, (54 + 1 - 52)
= (55-52)
= (3)
=3
Since we are left with one number, we drop the brackets.

STEP 2:
We solved our first set of brackets, we can put that value into the second set of brackets.
So,  {8 + 3 - (9 of 6 + 1- 13 x 4)}
=  {8 + 3 - (3)}
={ 8 + 3 - 3}    *Remember to drop the bracket.
= { 11 - 3}
= { 8}   * Since we are left with one number, we drop the brackets.
= 8

We have solved two sets of brackets. Now, we solve the last set of brackts,
[12 - {8 + 3 - (9 of 6 + 1- 13 x 4)}]
= [12 - {8} }
= [4]
= 4

So if you put the values in the sum as a WHOLE,
7 + [12 - {8 + 3 - (9 of 6 + 1- 13 x 4)}] 
= 7 + [12 - {8 + 3 - (9 x 6 + 1- 13 x 4)}]
= 7 + [12 - {8 + 3 - (54 + 1- 52)}]
= 7 + [12 - {8 + 3 - (3)}]
= 7 + [12 - {8 + 3 - 3}]
= 7 + [12 - {8}]
= 7 + [12 - 8]
= 7 + [ 4 ]
= 7 + 4
= 11
