I don't see how they are different. We can work with representations
('-a + a = 0', 'oo + 1 = oo', or we can work with the ideas
(negatives, where a number plus its negative is zero, orinfinity,
where adding 1 toinfinityresults ininfinity). I don't think one can
show a physicalinfinityand I think that's what you're saying (on the

it for negatives. (hm...I think I can do that too)

Suppose you have minus 500 Euro on your bank account ?
Then you owe someone 500 Euro.
So I guess -9 C outside means someone is owed 9 degrees.
Unless your thermometer is written in Fahrenheit.
What was the temperature of the Universe just before the Big Bang?
