In most program languages, operator precedence is algebraic. Exponents, multiplication/division, addition/subtraction and I believe all the comparison operations are lowest. The search term would be "operator precedence".
Operators of equal precedence are evaluated left to right.
Just as math in, -3+30/4 the variable u use tells the recision for int it would be 5 wich is wrong (4.5 is the answer) so u include iostream create main function , declare the variables and write the equation
