adamk · Answer

List the bigger negative numbers first. So, {-4, -3.2, -0.1, etc.} You do the rest.

adamk · Answer

Then start crossing out numbers from both sides of the list at the same time until you are left with one number in the middle.

anonymous · Answer

-4,-3.2,-2.3,1.9,-0.1?

anonymous · Answer

There's no -2.3 and -0.1 is in wrong place.

adamk · Answer

No. Remember negative numbers are always before positive numbers on the number line.

adamk · Answer

-2.3 is in the right place. Please do not confuse the person.

adamk · Answer

Except it is not -2.3. It's 2.3. So we have {-4, -3.2, -0.1, 1.9, 2.3}

anonymous · Answer

Yeah, that's what I said...

adamk · Answer

So what's the number in the middle?
