Disable "Last Answer" automatic insertion

[Benjamin]

Hello,

I apologize if this is already documented somewhere, but I could not find such a solution posted.

The HP prime will automatically insert the previous answer "Ans" if an operator is used without a value. I will include a screenshot from the quick start guide.

I would like to disable this functionality if possible.

Thank you! I am new to the prime, so I apologize if there is an obvious answer I am missing.
