= print produces the output the assignment statement produces no output order of operations when more than one operator appears in an expressionthe order of evaluation depends on the rules of precedence for mathematical operatorspython follows mathematical convention the acronym pemdas is useful way to remember the rulesparentheses have the highest precedence and can be used to force an expression to evaluate in the order you want since expressions in parentheses are evaluated first ( - is and ( + )**( - is you can also use parentheses to make an expression easier to readas in (minute even if it doesn' change the result exponentiation has the next highest precedenceso ** + is not and * ** is not multiplication and division have the same precedencewhich is higher than addition and subtractionwhich also have the same precedence so * - is not and + / is not operators with the same precedence are evaluated from left to right (except exponentiationsoin the expression degrees pithe division happens first and the result is multiplied by pi to divide by pyou can use parentheses or write degrees pi example for operator precedence / +( + = = = ( + )*( + )- ( + )* + - + **
