Ans problem

[periappi]

Hello,

I'm a young french student, so please forgive my eventual grammatical errors. I would know if it's possible to remove the "Ans" when you press the "-" key. Indeed, it is very annoying to get an "Ans" when I just want to type, for example : "-2+1" -> I'm forced to remove the Ans every time... Any solution ?

Thanks,
