Using PEMDAS you can figure out which part of the problem to do first.
PEMDAS=Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction
Since parentheses are first, you do 41-36=5
6[5*(41-36)-8+14)]
6[5*5-8+14)]
Next, you do the multiplication inside the parentheses. 5*5=25
6[5*5-8+14)]
6[25-8+14)]
Then you do the remaining subtraction and addition in the problem.
25-8+14
25-8=17
17+14=31
And you get 6[31)]
So you do 6 times 31 which is 186
