Answer 1

What's the 1st Negative Integer?

Answer 2

I'm not sure how do I find that out?

Answer 3

That's a tough question. Where shall we start?

I suppose the 1st MIGHT be considered -1 and the second -3, but that only makes a little sense.

Answer 4

I'm not understanding

Answer 5

What the first Positive integer?

Answer 6

Small wonder that you are not understanding. It is an unusual question that may not be well thought out.

I THINK it means, add -1 + -3 + -5 + ... + -19 + -21

Answer 7

The first negative integer is minus one; -1,
the second negative integer is minus two; -2,

the eleventh negative integer is minus eleven; -11.

Answer 8

Normally, we count things from the left. It is hard to do that with negative numbers. I dare you to find the left-most negative number.

The second negative number is -2 if we count from the right. Not sure why I was thinking ODD. :-(
