Your calculator is doing -3*3
You have to use parenthesis i think. (-3)^2 When in doubt I always use parenthesis.

20 years ago ( Has it been that long?) I was introduced to RPN. The guy explained how 5 enter 2 X to multiply 5 x 2. I thought it odd, but adapted. The he told what it was called, RPN. I said "you're kidding" This was when polish jokes were all the rage.

When I learned 2 + 2 = 4, I thought math was over.

-3^2 is indeed -9. What's PEMDAS?
By the way, this is an arithmetic problem. |

how can -3 be -9... a negative times a negative is always positive
Parenthesis Exponents Multiplication Division Addition Subtraction Please Excuse My Dear Aunt Sally |
