When an expression contains more than one binary operators, where the operators are identical or have the same precedence, the operators are left-assocative. This means that the expression is evaluated from left to right.
For example, the result of the expression shown below is 5, rather than 20. 80 is divided by 8 to get an intermediate result of 10. 10 is then divided by 2 to get a result of 5.
double result = 80 / 8 / 2;
This means that the above expression is equivalent to:
double result = (80 / 8) / 2;
If you want to force the division of the 2nd and 3rd operands to happen first, you could use parentheses around them:
// result = 20
double result = 80 / (8 / 2);
