Dividing by zero?

Why can't you divide by zero? This lesson looks at why division by zero is not allowed - not only is the answer undefinable, but seriously, if you do do it, a whole bunch of people on youtube lose it.

Back in High School I asked my math teacher why dividing by Zero is undefined, her answer, "It just is". Thank you for the clarification.

I'm weirdly excited that you're making videos again

[onderinozu]

the way you explain math makes it sooo straightforward! you re absolutely amazing

[anp]

Great video sir. Complex thing explained so beautifully
My son liked it a lot
Superbly explained
God bless you with all the best things...I mean it
Keep up the good work
Lots of love God bless

Well it’s just like if you have 1 x 0 = 2 x 0, cross the 0 out and you get 1 = 2, that’s not true, same in that case you can’t cancel out /0, because that means times both side by 0 and thus just get 0

So I have no candies and have no friends and you say that I can devide my candies into any number I want?
Infinity candies!!!!

Like your videos.. they make me think.. and learn. Thumbs up!

One time I asked my algebra 2 teacher why 0/0 didn’t equal 1. Her response: “what does your calculator say?” (Wow thanks that helps my understanding so much) Thanks for the explanation.

Undefined makes sense now. It cannot be calculated. Simple. Thanks KeepSmiling 😊🌺

Great work and analytical conclusions derived from the functions of basic numbers. I appreciate your efforts. Have a good day. Thank you.

Hey mate! We have been subscribed and watching your awesome videos for last 10 years. It would be really appreciated if you could improve the sound quality but loving your aussie accent heaps. Have a good day!

You should cover L'Hôpital's rule! :P

[jacquelinelawrence]

You are a absolutely amazing teacher . Thanks

So back to basics here, if I had 1 Apple and divided it by nothing...., I still have 1 Apple, so couldn't 1÷0=1?

[vinaygoel]

Very interesting and helpful
ps.love that your making videos again

I wrote the numbers from 1 to 19 next to each other, and thus form a very large number of 29 digits.
What is the sum of the digits in this number?

[tracyrain]

Wow! Nineteen Eighty-Four territory there, no? Is it possible that 2+2 could equal 5? My mind is blown! If you had been my teacher in school I would be ruling the world right now!!! 🤭 And it is lovely to put a face to the voice of awesomeness...😊

0/0 is indeterminate rather than undefined. A subtle distinction I know, but I'm just satisfying my own tendency to approach the limit of pedantry LOL!

I had a calculator that would say "infinity" when you tried to divide by 0.

Let's calculate 6/0
Let say :1/0=r while r is the remainder from the division.
6/0=6/1 *1/0 = 6r

0/0=0/1*1/0=0r

Now 8/3=2+2r/3 the remainder is 2/3
(We can always substrac infinity numbers of 0s from 8 items and it will always stay as it is 8 items. For any division's remainder if we multiply it by 1/0 it will stay the same .
Lets calculate
6/0+8/3=6r+2+2r/3=2+r(6+2/3)
=2+r(18/3 + 2/3) =2+20r/3

Let's aprove 6/0+8/3=2+20r/3
8/3-2=1/0 *20/3 -6/0
8/3-6/3=1/0(20/3 -6)=r
2/3=2/3r which is correct
Because quotient=0 and remainder is 2/3

Now
Let's calculate

6/2+1/0=3 +0r/2+1r= 3+1r


For a/0 I understand the concept about - > we can substract infinity zeros from a . but is that means that the quotient will go to the infinity. Why we should increment the counter of quotient
while we are not decreasing anything from a. Why we can't say the result is (quotient =0 and the remainder =a and the result =ra ).
