Hi, negative numbers don't have a real sqrt, as a sq is 0 or a positive. The sq of 0 is 0 and the sq of 1 is 1. Square roots of negative numbers

Regards Nick.

Hi Mike, I would have to shout really, really loudly or use a megaphone for Alexa to hear me, and I probably would hear her answer anyway.

Regards Nick.
