need to know which sign is greater than:< or >

> is greater than.

A good analogy is to imagine that the greater/lesser than sign is a mouth that always turns to eat the larger value.
1 < 2 -- One is less than two; the gluttonous mouth wants the bigger one, of course. ;)

8 > 3 (3 is more than 8)

3 < 8 (3 is less than 8)

The greater than sign (>), also known as the "greater than" symbol, is used to compare two values and determine whether the value on the left side is greater than the value on the right side. It indicates that the value on the left is bigger or higher than the value on the right.

On the other hand, the less than sign (<), also known as the "less than" symbol, is used to compare two values and determine whether the value on the left side is less than the value on the right side. It indicates that the value on the left is smaller or lower than the value on the right.

To remember which sign is greater than and which is less than, think of the shapes of the symbols themselves. The greater than sign (>), looks like an arrow pointing to the right, indicating movement in the "greater" or "higher" direction. The less than sign (<), looks like an arrow pointing to the left, indicating movement in the "smaller" or "lower" direction.

So, in summary, the greater than sign (>) denotes "greater than" or "bigger than," while the less than sign (<) denotes "less than" or "smaller than."
