Less than or greater than numbers 

Second method, how to remember.

Less than is `<`       greater than is `>`

Think of this: `<` or `>` as arrow heads

Examples

1.  `15<20`

Change to arrow head

15 `larr`20

The arrow is pointing to the smaller amount. 15 is smaller than 20, or 15 is less than 20.

2.  `10>6`

Change to arrow head

10 `rarr` 6

The arrow is pointing to the smaller amount. 6 is smaller than 10, or 10 is greater than 6.

3. `x>6`

Change to arrow head

`x` `rarr` 6

The arrow is pointing to the smaller amount. 6 is smaller than `x`, or `x` is greater than 6.
