A note about surds & negative numbers

[@RussellSubedi]

this is how you introduce complex numbers without introducing complex numbers.

[@DeJay7]

This is the nicest tease to imaginary numbers probably ever.

P. Lolol lol look ok to look0

[@supreme84x]

But zero is positive.

[@AchtungBaby77]

No it's not - positive numbers by definition are greater than 0 (located to the right of 0 on the number line) and negative numbers are less than 0 (located to the left of 0 on the number line). The number zero is therefore neither positive nor negative.

[@absolutelynot_here]

in france yes. in england no.

@@AchtungBaby77 I commented this awhile ago, but I think I was thinking of even vs odd, not positive and negative and mis-typed or just mis-remembered at the time. My bad.
