there is no unique solution for x−y=?.

yes it can dear professor thank you

you don′t agree that there is no unique solution?

dear professor, I think, x<y

$$\mathrm{dear}\:\mathrm{professor},\:\mathrm{I}\:\mathrm{think},\:\mathrm{x}<\mathrm{y} \\ $$

Commented by mr W last updated on 14/Nov/23

it doesn′t matter that x<y. but the question x−y=? has no unique answer. or do you have a problem with things like 2−4 ?

$${it}\:{doesn}'{t}\:{matter}\:{that}\:{x}<{y}.\:{but}\:{the} \\ $$$${question}\:{x}−{y}=?\:{has}\:{no}\:{unique}\:{answer}. \\ $$$${or}\:{do}\:{you}\:{have}\:{a}\:{problem}\:{with}\:{things} \\ $$$${like}\:\mathrm{2}−\mathrm{4}\:? \\ $$

in this question you can not determine x−y or y−x.

$${in}\:{this}\:{question}\:{you}\:{can}\:{not} \\ $$$${determine}\:{x}−{y}\:{or}\:{y}−{x}. \\ $$

Do you think the side (length) can be negative?

$$\mathrm{Do}\:\mathrm{you}\:\mathrm{think}\:\mathrm{the}\:\mathrm{side}\:\left(\mathrm{length}\right)\:\mathrm{can}\:\mathrm{be} \\ $$$$\mathrm{negative}? \\ $$

Commented by mr W last updated on 14/Nov/23

x <y means only that the side x is shorter than the side y. it doesn′t mean that the length of side x is negative !!!

$${x}\:<{y}\:{means}\:{only}\:{that}\:{the}\:{side}\:{x}\:{is} \\ $$$${shorter}\:{than}\:{the}\:{side}\:{y}.\:{it}\:{doesn}'{t} \\ $$$${mean}\:{that}\:{the}\:{length}\:{of}\:{side}\:{x}\:{is}\: \\ $$$${negative}\:!!! \\ $$

where did you get this bad question?

So the question (condition) is wrong...

$$\mathrm{So}\:\mathrm{the}\:\mathrm{question}\:\left(\mathrm{condition}\right)\:\mathrm{is}\:\mathrm{wrong}... \\ $$

a non−sense question.

$${a}\:{non}−{sense}\:{question}. \\ $$

Commented by hardmath last updated on 14/Nov/23

I posted it here to clarify that it was wrong...

$$\mathrm{I}\:\mathrm{posted}\:\mathrm{it}\:\mathrm{here}\:\mathrm{to}\:\mathrm{clarify}\:\mathrm{that}\:\mathrm{it}\:\mathrm{was} \\ $$$$\mathrm{wrong}... \\ $$
