Our friend doesn’t know what a mathematical proof is,

says person who doesn't know enough about Maths to prove the order of operations rules, which literally anyone can do for themselves if they know all the operator and grouping symbols definitions 🤣🤣🤣

will instead try to give you an example in which he posits a real-world calculation, writes down an arithmetic expression for it according to one convention, interprets it with another, gets a different answer, and tells you this is “proof” that it’s wrong

I have no idea who you're talking about, but it ain't me! 😂

writes down an arithmetic expression for it according to

the definitions of the operators 🙄

When I explained to him

was precisely nothing

how you could write down the expression according to a different convention, then interpret it with the same convention and get the same answer, he just denied, denied, denied

What you mean is I actually proved you wrong about "different conventions" (noted you still don't know the difference between conventions and rules), but you're pretending it never happened 🙄

And yet you were unable to reply with a proof. So sad.

Says person unable to point out in what way it wasn't a proof, so sad 🤣🤣🤣

I've given you the definition of a proof before, if you can't work out why what you wrote doesn't match you just can't do maths.

That's ok, as Barbie taught us "math is hard!"

I’ve given you the definition of a proof before

You gave the defintion of one kind of proof. I'll take that as an admission then that you can't fault any of my proofs, since you can't point out anything wrong with any of them, only that they don't use the only proof method you know of, having forgotten the other proof methods that were taught to you in high school 🤣🤣🤣

if you can’t work out why what you wrote doesn’t match

I already know why it doesn't match, that doesn't make it not a proof, DUUUUHHH!!! 🤣🤣🤣 You need to go back to high school and learn about the other methods of proof that we use. You only seem to know the one you use in your little bubble.

you just can’t do maths.

Says person who only knows of ONE way to prove anything in Maths! BWAHAHAHAHAHAHAHAHAHA! 🤣🤣🤣

Taken as an admission that I have indeed proved my points then, as I already knew was the case.

That’s ok, as Barbie taught us “math is hard!”

Is THAT why you only know ONE method of proof - you learnt from Barbie??? 🤣🤣🤣

You gave the defintion of one kind of proof.

All mathematical proofs can be written in that form, otherwise they are not proofs. All kinds of proof are merely special cases of the general kind I told you about. You didn't know this?? Yeesh.

says person confirming he doesn't know much about Mathematical proofs 🙄

All kinds of proof are merely special cases of the general kind I told you about

No they're not, and you even admitted at the time that it had limitations 🙄

You didn’t know this?? Yeesh

Yes, I knew you only knew about one kind of proof, hence why I told you to go back to high school and re-learn all the other types that we teach to students

Hahaha ok sure thing buddy!
