# this isn't relevant to this part of mathematics, but, in a calculator, would the calculator automatically solve a problem using order of operations to get the correct answer? ⚑ Flag

A  calculator does follow the "PEMDAS" rules when executing an expression, yes.

Yes, calculators are programmed to use order of operations.  However, in intermediate and advanced mathematics you need to be sure that you have entered your parenthesis properly or you will get an incorrect answer.  This is especially true when using in trigonometry and when working with exponents.

The calculator would automatically solve the problem using order of operations because calculators are made to do that. For example:  If you had,   3(8-6)+8÷8= unknown answer Calculator answer: 7 (i put in the equation just as it is on the calculator but if the equation has parenthesis make sure your calculator has a parenthesis button.) My work:   3(8-6)+8Ã·8=?    3(2)+8Ã·8=?        6+1=?         7=7

Only if you've entered it with correct parentheses. If you simply type it out, the calculator is programmed to solve information in the order it's received.
