Why can't I use my spreadsheet?
Why can't I do it in my head, as ignorant Basque shepherds did?
How will you know if the answers we feed you are correct?
...better you should use your calculator to evaluate the expression. Don't forget to at least check your answer by estimation at least.
Here are the keystrokes:
[ 2 ] [ . ] [ 3 ] [ 1 ] [ - ] [ 5 ] [ . ] [ 0 ] [ 3 ] [ +/- ] [ * ] [ 7 ] [ . ] [ 7 ] [ 9 ]
(When I got to the - sign, the point of the exercise became clear. Do you see it yet?)

A. -3.20697 = (z^2) / (xy) "priority of operations" would desire to confirm *the place* you place the parentheses. in case you utilize z^(2/(xy)) you get a complicated selection, which maximum calculators won't evaluate .. in view that taking a unfavorable selection to a "fractional" exponent power is very generally "underfined" which, lower back, amost continually ability "complicated selection" your question is in accordance with an erroneuous assumption of operator-priority .... very ambiguous. sturdy success

My calculator says x - yz = 41.4937.
Rounding to the nearest tenth is 41.5.
