Doh! I don't know where I got the '+1' from.  You are correct as the equation in the OP is written.

Ink, I need to brush up on my vector calculus. When are you free?

MA+A=AM
(M+1)A=AM
A=0

Without the context of the problem this is the only way I would have ever interpreted it.

This is a typical question in the SAT math section. Just saying

I wouldn't know. On every multiple choice test involving variables like this I always just plugged in the answers until I found one that works.

That way I didn't have to waste time debating about whether the question is completely useless or not.  :aok

Not even remotely equal.

As long as something is probable, however unlikely, you can assume it could happen. But you can't take for granted something will happen, no matter how probable it is, as long as there is a chance it may not.




ok i understand that, but if you assume the possibility exist that it is solvable you are not taking it for granted its just a possibility,.. open mind one way or the other.

I kinda got lost, so I asked for translation...

Me: Do not assume it's red.
You: Why not?
Me: There are many which aren't red, so it could be blue.
You: There are even more which are red. By your logic you should assume it's red. Your answer is wrong.
Me: Trying to explain myself...
You: I get you, but you should be more open minded.

Thanks, I'll do my best.

just realised my solution wasnt complete as M can also be any complex number, not just real numbers. so, maths guys, are there any numbers which wont work as M? :headscratch:

Well not really, not without losing a lot of properties, and really being a poor definition of number in general.  Something like IEEE 754-2008 has the property that 0 * Inf = NaN, but this is stretching the bounds of your question.  All the numbers we would ever use like the reals, integers, complex, rationals, etc, will follow the field axioms.  I get the feeling bighorn knows more about math than I do, so if I'm wrong on any of this I default to him...

So basically, no.
