    You absolutely have to use a scientific calculator to input the whole equation before calculating anything.

    And thus is the rub.

    The math situation is solved from whereever you were taught in the world. That is how you solve it. The answer is still the same.

    Incorrect

    The way you have it written you would have

    (8)(20)40-30=6370...

    8×20×40= 6400

    6400-30=6370

    To get the answer you came up with the equation would have to be written

    (1+7)(2×10)(40-30)=1600

    Take the multiplication sigh out from in between the 2 and (... You have to imput it just exactly like the equation is written.

    And even then I'll bet most cheap calculators or phone will get it wrong.

    Look at the next pic... or use a TI 85 emulator or TI 85... 2(4) is the same thing as 2x(4)
