Exclamation trouble with multiplication

I have found a flaw (I'm sure I'm not the ONLY one).

Now in my understanding of math is of < or > or = to etc. etc.
and I also realize the difference to physical proof to theoretical proof from what math seems to be based on (in my opinion).

Also to be considered is that Occam's razor DOES NOT always work. Why? Because of Murphy's law. (Do you know this??) So knowing things go wrong while accepting the simplest answer it tells me that SOMETHING is wrong!

I know this sounds like wacky mumbo jumbo, but well it's the nature of the beast, so to speak.

Anyways....

0x5=? 0? right
5x0=? 0? right? I say wrong, and I have PHYSICAL proof.

I know this will get some flack, but I'll let this sit here so people can see it.

PLEASE don't be shy and let's get to the bottom of this.

I am very serious and this is NO WAY an attempt to insult anyone!

I just want my windows OS to work flawlessly and until we get all the CONTRADICTIONS in mathematics it will never be flawless.

Thank you for making it through this spiel and look forward to any and all sides of criticism.

Google suggests 0 for 5x0, but not for 0x5.

What d'heck going on? Is x a multiplication symbol?
If so, why? Google gives 0 for both 5*0 and 0*5.
Also, google treats 0x5 as an error code.

When using octonions, for example.

Is there supposed to be any proof or evidence in your OP? I must have missed that.

And there you go.

But I am still waiting for the "physical" proof that $a * 0 \ne 0 * a. $

No, you missed nothing. There WAS an assertion that a "physical proof" existed, but the OP overlooked supplying evidence for that assertion. I am confident that the oversight will be corrected at any moment.

That looks like notation for a hexadecimal number.
