Question

can you divide by zero? Why or why not?

Answer 1

@babyx3boo.

Answer 2

what do you think ??

Answer 3

I think no

Answer 4

Anything multiplied by zero will always equal zero :)

Answer 5

of course you can

3/0, i just did it, the thing is, what does it represent?

Answer 6

Try it in a calculator. If the zero is in the numerator, the answer will be zero. If the zero is in the denominator, the result is undefined and you may also see an error message

Answer 7

yes you are right you divide by zero result always going to be
undefined \[\frac{ x }{ 0 }=\] undefined
like in real life

Answer 8

can't*

Answer 9

its not that is undefined, its just that it needs to be defined for the application

Answer 10

For an elementary example: If you had 2 oranges and divided it by 0 people, how many oranges would the people get?
Answer: Zero! Because there are no people in the first place :P Nobody would get anything

Answer 11

if you define 1/0 = infinity, then youve defined it and it has meaning in application

Answer 12

@nuccioreggie I think you get it now, we're all just still ranting xD

Answer 13

i dont rant ...

why oranges ??
why not chocolates ?

Answer 15

division by exactly 0 is not allowed <---- that is one of the rules of division

Answer 16

i tried it once

Answer 17

@Nnesha That. Is a very good question.

Answer 18

division by zero is meaningless without a properly defining it within an application

Answer 19

had to lie down for a week, almost lost my arm

Answer 20

lol

Answer 21

i was trying to figure out how many miles per gallon i got on my bicycle

Answer 22

division by exactly 0 is not allowed when you learned division, if you ever did, way way back in earlier years, you also learned that rule

Answer 23

i went 20 miles using no gallons of case
tried to compute \[20\div 0\] and almost ended up in a hospital

Answer 24

tan(90) is the slope of a vertical line ... which is n/0

Answer 25

Lol yea i think you cant divide by zero it dont make since

Answer 26

YES!!! 3/0 = 0
5/0= -
EVERYTHING divided by 0 is 0 :)

Answer 27

0 is just an ugly number, no one wants to get divided by it :(

Answer 28

technically tan(90) is undefined and so is the slope of a vertical line

Answer 29

3/0 = is not equal to 0
\[\frac{ 0 }{ 3 } =0\]

Answer 30

I would argue that all of calculus is the very careful study of how we can usefully and precisely divide zero by zero haha. Something to look forward to.

Answer 31

Every operation between two numbers must have a unique solution.

Division is defined in terms of multiplication.
Division is defined as: \(c \div a = b\) if and only if \(a \times b = c\).
For example, \(10 \div 2 = 5\) is true only if \( 2 \times 5 = 10\).

Now let's try dividing by zero:
\(x \div 0 = y\) means that \(0 \times y = x\)
This is not true in general.
For example, \(10 \div 0 = x\) only if \(0 \times x = 10\), but there is no number x which when multiplied by zero will result in 10.

You could say then that there is no division of a nonzero number by zero, but maybe you can divide zero by zero.
\(0 \div 0 = 0\) since \(0 \times 0 = 0\)
The problem here is that the quotient in this case can be any number, since
\(0 \times x = 0\) for all x.

There is no division by zero because
1) when dividing a non-zero number by zero, no number works in the multiplication, and no answer can be found.
2) when dividing zero by zero, every number works in the multiplication, and there is no unique answer.
