What's a greater number than -1? Is it -1.1 or -0.9?

to get a number greater than a given number add a positive value to it.

-1 + 0.1 = -0.9

-1 < -0.9

on the other hand to get a number less than a given number subtract a positive value from it

-1 - 0.1 = -1.1

-1.1 < -1

-0.9
think of a number line, -0.9 is to the right of -1, so it's greater.
In a number line (or x-axis in cartesian graph), if you go to the right, the number is greater.

What is the smallest positive number?

#### EvanJ

In my opinion, 1/infinity should be defined as the smallest positive number.

$$\displaystyle \frac{1}{\infty } \rightarrow 0$$.

Except that $$\displaystyle \infty$$ is not actually a number....

It would be better to say $$\displaystyle \lim_{x \to \infty} \frac{1}{x} = 0$$.
