1. I knew that 0 cannot be divided by any numbers.

2.But I did not know why 0 could not be divided by any numbers

# data[].attributes.body
I know that you cannot divide by 0.

I learnt that if 0 times infinity = 1, (0 x infinity)(0 x infinity) must be equal to 2, but the said equation can be simplified to 0 x infinity = 2, so 0 times infinity = 1, and 0 times infinity = 2, but that is not correct.

I learnt that there is a term called "multiplicative inverse" and "Reimann sphere".

1. I knew that zero cannot be divided

2. I learnt that since zero doesn’t have a multiplicative inverse hence it can’t be divided

3. A new term I learnt is the Riemann Sphere which is a different way of diving with zero

# data[].attributes.body
1. I know that it is not possible to divide by 0

2. I learned what a multiplicative inverse is

# data[].attributes.body
I knew that dividing into zero is impossible as the answer will always be zero

Dividing by smaller and smaller numbers give you bigger and bigger answers

Multiplicative inverse

# data[].attributes.body
1. Before watching the video, I used to think that the reason that you couldn't divide by zero was as simple as the fact that anything divided by zero would equal to infinity because there you would need infinite 0's to form any number

2. I learnt that its not so easy to divide by 0, as 0 does not have a multiplicative inverse, unlike all other numbers, whose multiplicative inverse is 1 out of itself. So, zero's multiplicative inverse would be 1 out of 0, and 0*1 out of 0, would be 1. Unfortunately, anything multiplied by 0 is 0. Hence, 0 has no multiplicative inverse. So basically 0 is not a number. Wow.

3. I learned the term, "Multiplicative inverse" ✨✨✨

# data[].attributes.body
1. I knew that dividing by 0 is impossible.

2. I learnt that there is something called the Riemann Sphere that involves dividing by 0 using a different method.

3. The multiplicative inverse.

# data[].attributes.body
1. You just can't divide anything by 0.

2. You still can't divide anything by 0 at least until now.

3. Distributive method.

# data[].attributes.body
i learnt that you cannot substitute 1/0 for infinity symbol as it will mean 1=2

# data[].attributes.body
i learnt what a mutiplicative inverse is

# data[].attributes.body
i knew that anything multiplied by 0 is 0 so i assumed it was same for division

# data[].attributes.body
I knew that when we divided by zero we were dividing into zero groups so the answer can’t be anything

I learnt that mathematicians broke math rules before

Multiplicative,

# data[].attributes.body
I learnt the term, multiplicative inverse.

# data[].attributes.body
I learnt that I cannot divide by zero as to divide by a number, that number must have a multiplicative inverse, and zero does not have a multiplicative inverse.

# data[].attributes.body
I knew that you cannot divide by zero, but did not know why.

# data[].attributes.body
1. I know that if you type a number divided by 0 the calculator will show a calculation error on the screen

2. The multiplication inverse of 0 is 1/0, and 1*1/0 should equal one, but anything times zero is zero, so it may mean 1=0 or zero basically doesn't have a multiple inverse

3. A new term I learnt is: “multiplication inverse”

# data[].attributes.body
1. I knew that you would get a math error when a number is divided by zero on a calculator.

2. I learned why a number cannot be divided by zero.

3. multiplicative inverse

# data[].attributes.body
Dividing by zero is inherently impossible as dividing requires that you do exactly that - dividing a piece into pieces. But a piece is 1, singular piece. How can you divide a piece into no pieces? Thinking critically, the only plausible answer would be infinity, but that is a stretch in of itself.

# data[].attributes.body
I learnt that zero has no multiplicity inverse.

# data[].attributes.body
I knew that any number divided by zero leads back to zero

# data[].attributes.body
1 cant divide by 0 because how would that work at all

2 ok im confused now but i still believe that divide 0 is just wrong but ok

3 multiplicative inverse

# data[].attributes.body
Square root of -1 is i

# data[].attributes.body
Multiplicative inverse x number is 1. 0 doesn’t have a multiplicative inverse

# data[].attributes.body
I know that dividing is splitting into parts you can’t split to 0 parts.

# data[].attributes.body
A new word I have added to my vocabulary is multiplicative inverse.

# data[].attributes.body
I have leant how a multiplicative inverse works.

# data[].attributes.body
I knew that a number could not be divided by zero.

# data[].attributes.body
because anything times 0 is equal to 0 so it's basically impossible to divide by 0

# data[].attributes.body
I learnt what a multiplcative inverse is

# data[].attributes.body
1 i knew that when you divide something with zero the answer would always be zero

# data[].attributes.body
1. i knew that dividing a number by zero would not result in a definite answer

2. i learnt that the product of every number and its multiplicative inverse equals to 1 (e.g 3 × 1/3 = 1) but zero does not have a multiplicative inverse as nothing multiplied by zero equals to 1 (it only equals to zero)

3. some new terms i learnt from the video are multiplicative inverse and the Riemann sphere (which involves dividing a number by zero with a different method)

# data[].attributes.body
The multiplicative inverse of 0 does not exist

# data[].attributes.body
Multipletive inverse and the riemann sphere

# data[].attributes.body
I learned that zero has no multiplicative inverse as even if it did. Like1/0 1 would be equal to 2 which is wrong.

# data[].attributes.body
I thought that you would get zero if you divided any number by zero.

# data[].attributes.body
Q1. I knew that dividing by zero gave you math error because is not possible to divide by zero.

Q2. I learnt that zero does not have a multiplicative inverse and if we break the rule and say 1/0 is infinity, 1 would be equal to 2, which is wrong.

Q3. I learnt what a multiplicative inverse is.

# data[].attributes.body
Multiplicative inverse

# data[].attributes.body
The product of any number and its multiplicative inverse is always one

# data[].attributes.body
I thought that when you divide something by 0 there is no answer

# data[].attributes.body
Multiplicative inverse

# data[].attributes.body
I learnt that when you divide, you can always multiply the answer by a fraction of the first number to get back the first number. However this does not work for zero as any number multiplied by zero is still zero.

# data[].attributes.body
I knew that any number divided by zero would have no answer as you cant divide some thing into 0 groups and find out how many groups there are
