Hello everyone,

I know from the power property that log(10^-12) should be -12. Wolfram-Alpha corroborates this.

However, when I evaluate this on both my HP 15C and 50g, the answer turns out to be -11. Here are the exact keystrokes I am using for my 15C:

10

EEX

12

CHS

g

LOG

Any ideas why this might be?

Thank you,

Daniel
