'Why is six afraid of eight? Wait, I messed up the joke.' : Logic Based Maths Problem And Its Solution

8   8   8   8 

How do you make this equation true by only using mathematical operators like addition, subtraction, multiplication and division and parenthesis? You can't touch the right hand side of the equation.

A as the number of addition signs used, 
B as the number of subtraction signs used, 
C as the number of multiplication signs used, 
D as the number of division signs used, 
E as the number of (sets of) parentheses used.

Submit your answer as .

Details and Assumptions:

As an explicit example, if the equation is , then  and your answer is 02111.
Use as little parenthesis and addition signs as possible.
Binomial coefficients don't count.
BODMAS is applied.

Problem Source:Brillaint

8 - (8 + 8) ÷ 8 = 6

Please keep in mind that I have not written 8 - {(8 + 8) ÷ 8} = 6 since it is given in the rules that BODMAS Rule is applicable.So,according to the code given,A = 1,B = 1,C=0,D=1,E=1.

So,the answer has to be expressed as 11011.
