Hi sonrich,
The ">" symbol is used to show that the value at the left of the
symbol is greater than the value at the right of the symbol, as in:

2 > 1
10 > 6

According to a post in the Ask Dr. Math Forum, the mnemonic often used
to remember this is "...an alligator - which is notoriously hungry -
always wants to eat the larger number.
     3 < 8   Alligator wants to eat the 8, so 3 is less than 8
     5 > 2   Alligator wants to eat the 5, so 5 is greater than 2"

Although that's how it's mainly used, you can sometimes find that
symbol with only one number at its right (and no number at its left),
as in "> 30". This actually means "greater than 30". For example,
consider an hypothetical table that shows the number of people of a
certain age in a country:

Age     |    Number
-------------------
0-10    |   20,000
11-20   |   25,000
20-40   |   22,000
40-60   |   20,000
 >60    |   10,000

This means that there are 10,000 people more than 60 years old.
Similarly, if you see for example "< 30", this would mean "less than
30".

I hope this helps!

">" if read left to right, or right to left, has two sides:
One side is wide or open.
The other side is very narrow or closed or pointed.

Anything on the side that is wide or open is greater/bigger/wider than
anything on the closed or pointed side. And vice versa.

x > y
That means x is greater than y.
It also means y is less than x.

x < y
That means x is less than y.
Also, y is greater than x.
