Does your calculator follow the steps for simplifying an expression stated on previous material?
Experiment with your calculator by entering the following example exactly as it appears here :
8 + 3 x 4 = ...
If your calculator displays the answer 20, it followed the order of operations you learned : multiplication before addition. Your calculator has an algebraic operating system. The answer 20 is correct.
If your calculator displays the answer 44, it performed the addition and the multiplication in the order in which you pressed the keys. One way to get the correct answer on your calculator is to multiply 3 and 4 first and then add 8, just as you would if you were using pencil and paper.
