What Does The Infinity Symbol Mean?
Infinity definition: an abstract concept describing something without any
limit. Wow that is a mouth full. What does it mean? Infinity means
"goes on forever". Can something go on forever? Every road has an end. Every stair
case has an end. Well numbers are a little different. Let's look at numbers.
First let's define the infinity sign: ∞. Start at zero and going forward:
0 + 1, 1 + 1, 2 + 1, 2 + 1, 3 + 1, 4 + 1, ... This looks a little odd. Take a number add one
to it and you get the next number. If you do this forever (there is no end to numbers)
you get infinity: 0, 1, 2, 3, 4, 5, .... ∞. One more important
fact. Infinity is true for both positive and negative numbers.
