Question

what is the conjugate of a+b?

Answer 1

a-b

Answer 2

really?

Answer 3

is the conjugate of
\[3+5\]
\[3-5\]?

Answer 4

well, do you know what the conjugate is?

Answer 5

yes i think so
3+5 = 8 and the conjugate of 8 is 8
3-5=-2 and it is also its own conjugate

Answer 6

the conjugate of
\[a+bi\] is
\[a-bi\] for complex numbers
and the conjugate of
\[a+\sqrt{b}\] is
\[a-\sqrt{b}\] if you are talking about real numbers

Answer 7

so what is the conjugate of a+b

Answer 8

but i have never heard of the conjugate of
\[a+b\]

Answer 9

3 + 5 = 8
2 + 6 = 8
is the conjugate of 3 + 5 3 - 5? this makes the conjugate of 8 as -2

Answer 10

Answer 11

what nonsense. the "conjugate" of 2 + 3 is certainly not 2 - 3

Answer 12

this makes the conjugate or 5 into -1 and also of course since 4+ 1 = 5 apparently 5 has multiply conjugates.

Answer 13

well, go write a letter to someone

Answer 14

lol

Answer 15

what do you think the answer to this question should be

Answer 16

it doesn't have an answer if a and b are unspecified.

Answer 17

in the complex number system the conjugate of a real number is itself

Answer 18

I understand what you mean, but this guy's teacher is is probably expecting a-b as the answer

Answer 19

so how in god's green earth can the conjugate of
3 + 2 be 3 - 2? makes no sense whatseover

Answer 20

that i believe! there is no end to bad math instruction

Answer 21

every number would have an infinite amount of conjugates right?
-1+6 has conjugate -1-6 and also 2+3 has conjugate 2-3 etc. so 5 has an infinite number of conjugates by this wingspaneyed definition

Answer 22

i fourtunatly made it out of one of the worst public school systems in the county, and i know that his teacher is not expecting him to come back to school and say that he wont answer the question because the a and b are unspecified. The teacher probably does not even know what that means

Answer 23

well i had the distinct pleasure of teaching high school math teachers to prepare for exams, and also to get degrees. very nice people for the most part, but man oh man their idea of math and their background in it would make you cringe

Answer 24

what can i say, most teachers graduate with degrees in education not mathematics

Answer 25

at least that has been my experience in Chicago

Answer 26

so sadly true. that is why people learn to multiply two 2-digit numbers together by sticking them inside a box

Answer 27

are you indirectly talking about me

Answer 28
