Question 1017057
"The calculator says 4*y*x*y=4xy^2 but I get 4y^2x, why does x come before y^2."
Both are correct. It might be more standard to "alphabetize" variables.


"The calculator says -2^4=-16 but I get 16, why is the answer negative?"
Because you are raising 2^4 and then multiplying it by -1. However (-2)^4 is equal to 16.
