Doesn't 0 divided by 0 equal 0? I mean, if you think about it, 3/0=0 =, 2/0=0, and 1/0=0. So why doesn't 0/0 equal 0?

bro 3/0 does not equal 0 the closest answer is ∞, but mathematicians aren't sure!

they think that x/0=∞ where x>1 because:

 

5/0=x

0*x=5

 

x=2?

0+0=0

x=3?

0+0+0=0

x=12?

0+0+0+0+0+0+0+0+0+0+0+0=0

 

no matter how large x the answer is still 0! ( btw this ! is an exclamation not a factorial sign cheeky)

 

anyway, back to 0/0, this one is extra confusing. you may think: "simple! x/x=1 so 0/0 must also = 1!"

 

but no. write it as a formula: 

0/0=1 

simplify

1*0=0

makes sense right? but what about

0/0=2

2*0=0

why this also works!!

0/0=3

3*0=0

rinse and repeat:

0/0=4

4*0=0

oh and don't forget:

0/0=0

0*0=0

so there you have it. yes, 0/0 is 0 but at the same time it isn't

You have it backwards. 0/1 = 0. 1/0 = undefined.

 

 

But 0/0 can't be zero for multiple reasons. If you divide a number by 0, it would be like 0e+0, which is technically undefined.

3/0, 2/0, 1/0     don't  = 0  ........these are undefined

 

0/0  is known as "indeterminate"

 

 

cool cool cool
