Question

What does/can this mean \[b|a\]

Answer 1

conditional probability?

Answer 2

b divides a

Answer 3

3|24

Answer 4

a is the multiple of b

Answer 5

also, bitwise or

Answer 6

"b given a" or "b such that a . . ."

Answer 7

hmmm it has a diff meaning. I forgot what it was though. Something confusing that is forsure

Answer 8

Might be part of a Bra-Ket as well...

Answer 9

Answer 10

hahahahah ok gonna go get my book.

Answer 11

I messed up. I got it confused with \(A|_B\)

Answer 12

By itself like that, I am more inclined to go with 'a divides b.'

Answer 13

and now that I think abt it if its referring to numbers then hartnn's explanation is correct

Answer 14

er, right 'b divides a'
forgot the order for a sec..

Answer 15

I have a feeling that the topic is Relations so ya it wld be referring to the dividing

Answer 16

Who knows. Unkle is the kind of guy who will try to tell you that 0×∞ = -1, so it could mean anything to him.

Answer 17

hahahah true but I know he is taking some course similar to discrete math so that one of the topics covered

Answer 18

i love that sign

Answer 19

according to course im taking \(b|a\) means
\(a\) is divisible by \(b\)

which is values of either true, or false

Answer 20

Ok, that's pretty standard then.
Here's a fun fact, in typology, the '|' symbol is called the "pipe."

Answer 21

hey i knew that

Answer 22

Oh That is an awesome fun fact :P

Answer 23

I kinda made up that word, "typology," though; apparently that already means something else.
What I meant was "type-setting."

Answer 24

I misread that as topology -_-

Answer 25

study of typing

Answer 26

They should totally create a study group for typology

Answer 27

is seven divisible by zero \[0|7=\]

Answer 28

false?

Answer 29

U cant divide by 0

Answer 30

Like it will just go to infinity

Answer 31

@swissgirl positive infinity or negative infinity?

Answer 32

Zero doesn't divide anything.

Answer 33

good question @CliffSedge lol

Answer 34

is zero divisible by nine
9|0=

Answer 35

One also doesn't divide anything since it leaves the dividend unchanged.

Answer 36

yes it equals 0

Answer 37

so true?

Answer 38

Well I would say its true but I am not the kind of person u can rely on

Answer 39

and \[1|1\]is false @CliffSedge ?

Answer 40

Zero is divisible by everything, but I wouldn't say that zero is *divided* by anything.

Answer 41

Nope that would be true 1|1 is true

Answer 42

1/1=1

Answer 43

but...

Answer 44

There is a difference between "divides" and "is divisible by."

Answer 45

i would say , just do a/b
if that comes out to be integer , then true, else false

Answer 46

^ that's a good computer-science algorithm

Answer 47

so

0|7 F
9|0 T
0|0 F
1|1 T
7|44 F
7|-42 T
-7|49 T
-7|-56 T

Answer 48

Correct

Answer 49

b|a

is b a factor of a

Answer 50

Yes I would say sooo

Answer 51

yes

Answer 52

hmmm the only one which seems like it isnt is 9|0

Answer 53

How can 9 be a factor of 0 unless anything can be a factor of 0

Answer 54

Being a factor and being a divisor are two different things (but that distinction might not matter in the application you are using).

Answer 55

Can 9 be a factor of 0 @CliffSedge

Answer 56

Yes. 9 × 0 = 0.

Answer 57

Gotcha

Answer 58

thanks everyone

Answer 59

Nicht kein problema
