−90.1=−90
−90.01=−900
−90.001=−9000
−9n approaches−∞ as n →+0
BUT n can approach 0 from above or below.
−9−0.1=90
−9−0.01=900
−9−0.001=9000
This time
−9n approaches+∞ as n →−0
n cannot approach -infinity and +infinity at the same time and end up at the same place so -9/0 must be undefined. I think indeterminant is the more common term these days but to the best of my understanding both terms mean the same thing.
Does that make sense to you?
+3454 -9/0
-9/1 ÷ 0/0
-9/1 * 0/0
-0/0
= 0
I'm not entirely sure if this is correct because I tried it on two different calculators. One said ERROR and the other one said -Infinity.
...?
Any number divided by 0 (zero) is undefined. This includes 0/0.
It is NOT infinity nor negative infinity.
The calculator that returned "-Infinity" is wrong!

+259 Ooooops I must be confusing with this limx→0cx=∞ c=const. Really sorry, I'm just hooked on maths analysis recently.
