36/4+5-1+2x3+12/3+1=6 Insert parenthesis and other group symbols.
If the expression is evaluated as is, it will give a value of 24 using the usual rules of priorities of operations.
Parentheses can be used to modify the values, for example
36/(4+5)-1+2x3+12/3+1 = 14
36/4+5-1+2*3+12/(3+1) = 22
Try other ways of putting parentheses and you will get it. You only need to put one pair of parentheses for this particular problem.
