Well then I do not know how to use my calculator. Every time I put in -3 to the second power it gives me -9. I have tried more than one calculator.


Clear your calculator, punch in 3, hit the "change sign key", then hit the squared button. OR, punch in -3 and multiply by -3.

try putting brackets around -3 on your calculator, or

knowing that when you square a negative you get a positive, why not put in the positive value of your number to begin with?

Thank you. Using brackets fixed my problem.

    3(-5)squared -2/-5(2)/2 squared I don't get the second part but... any number squared is positive so 3(-5) squared is 3x25 if only (-5) is squared. If the whole thing is squared then multiply first, (3x-5) then squared the answer.
