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.

Define 
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.
