Having one IS either side. As in, either/or.

No it's not, you CANNOT CHANGE THE MEANING OF A MATHEMATICS SYMBOL TO SUIT YOUR NEEDS.

It is what it is...

> = greater than

< = less than

The link in the other post tells you this quiet clearly...

Aaaaaaargh.....No they don't!!!!

30>60 STILL means "30 is greater than 60", but that doesn't make the expression TRUE!

You can say "a cow is bigger than an elephant", that doesn't make it true!

I'm going to go lie down in a dark room after this.

Actually, I was going to suggest you do that, Max, before you blow a fuse. I am going to go food shopping - much more relaxing than this.

It also means that 60 is less than 30. And that is also false.

Enjoy your nap.

But we read left to right!!!!!!! The sign is read left to right! You can't just change the meaning of a sign because you are reading it the wrong way!

> means greater than, and < means less than. That's it. It's a fact. FACT.

I will say it one more time. Yes it does.

you need the ... on EITHER side to quantify it.

Just as 5>3 means '5 is greater than 3' it ALSO means that '3 is less than 5'.

Oh my...I give up...

No, you can IMPLY that '3 is less than 5', but it means '5 is greater than 3'

Indeed.

What you are talking about here is what we call "mathematical equivalence". Therefore:

5 > 3 (five is greater than three)

Is equivalent to

3 < 5 (three is less than five)

In mathematics, "equivalent to" does not quite mean "the same as".

There's no need to be quite so rude.

Not everyone in the world was taught maths reading from the left to the right.

For me, I see '>' meaning that the thing on the left is greater than the thing on the right.

> on it's own is meaningless until something is on either side.

With all due respect, I am allowed to see that, as this is how I see things.
