1. I knew that dividing a number by 0 is not possible because there is no possible amount of groups of 0. For example, if you want to divide 5 by 0, it is impossible since even if you add a billion 0s to each other, it will still be 0 and would never add up to  5.
2. You can’t divide a number  by 0 because 0 has no multiplicative inverse

1) I thought that anything divided by zero is infinity        2)the only way that that a number can be divided by zero is by making all numbers equal to zero hence it is impossible to divide by zero                                           3) inverse

1.) Before i watched the video, I knew you can take the square root of negative numbers.

3.) Multiplicative inverse.

Before watching the video, I already knew that it was impossible to divide anything by 0.

After watching the video, I learnt how to explain the reason why it is impossible to divide a number by 0, as it would cause chaos and mess up all the existing knowledge we already had on numbers

A new term I have learnt is "Multiplicative Inverse"

# data[].attributes.body
1. I knew that zero was impossible to be divided by.

2. I learnt that if any number(x) could be divided by 0, then that number would have to be multiplied by 0 to achieve the desired output. Example: 6*0=0*1/0.
However, if that were to be true, then 0=1. 0=1 is false, the statement is not true and nothing is divisible 0. OR
0*Y=1. Y represents a value that meets the statement of dividing by 0. That means (0*Y)+(0*Y)=2. However, after simplifying the statement above, we come to a conclusion that 0*Y=2. Due to the previously solved equation that 0*Y=1, this clashes with 0*Y=2, making the only way a number to be divided by 0 is if all numbers equal all other numbers, which is impossible. Therefore it is impossible to divide by 0.

3. I learnt about multiplicative inverse, which means 1 over the number.

Before the video, I knew that any number divided by 0 would be zero since there was nothing to divide by.
After watching the video, I learnt that you cannot divide by zero as zero did not have a multiplicative inverse

2) Zero has no multiplicative inverse.

I knew that we could not divide something by zero.
I learnt that you cant divide something by zero as the number would just be infinite.
1 New term I learnt was "zero has no multiplicative inverse"

# data[].attributes.body
i initially thought that dividing by 0 equals to infinity but after watching the video i realized that dividing by 0 can be equal to nothing and something at the same time. i also learned that mathematics is also like a sandbox for mathematicians to play around with rules and numbers to see what can happen.

Zero does not have a multiplicative inverse

I knew that any number divided by 0 is always 0. I always look at it as a number of items, put into 0 groups, therefore that group has 0 objects. From this video, I learnt that 0 has no multiplicative inverse. Therefore, no matter what number you took and divide it by 0, it will always be 0. Some new words i have learnt is 'multiplicative inverse'.

# data[].attributes.body
1. I knew dividing by zero would give you nothing as it has no numerical value.
2. I learnt that Square root of a negative number is possible, sometimes we need to break the laws of Math to find new concepts, using a riemann sphere which divides using zero in a different way
3. I learnt what is multiplicative inverse of a number and a riemann spher

1.) I knew that you could not divide by zero

2.) I have learned that zero has no multiplicitive Inverness and and that any number multiplied by it's multiplicitive Inverse is always one

3.)I have learned the new term "multiplicitive Inverse"

# data[].attributes.body
1. Before watching the video, I only knew that whatever is divided by zero would have a result of zero.
2. After watching the video, I learned that we cannot divide by zero as it does not have a multiplication inverse.
3. multiplicative inverse

# data[].attributes.body
1) Before watching the video, I don’t really know exactly why and how to explain but I knew that you cannot divide something by zero as it is meaningless to do that because if you divide by zero, there won’t be any ‘groups’. (Eg. If 5 divides by 1, there would be 1 group of 5. But if 2 divides by 0, there will be 0 groups of 2.) Hence it isn’t possible to divide anything by zero.

2) After I Watch the video, I learned that we cannot divide by zero as zero doesn’t has a multiplicative inverse as the product of any number and its multiplicative inverse should always be 1 but since the product any number when multiplied by zero is always zero, there isn’t a multiplicative inverse for zero. With that, we cannot divide a number by zero.

3) A new term that I have learned from the video is ‘multiplicative inverse’.

1.I knew that any number that wasn’t 0 divided by 0 was 0
2.i learnt about the multiplicative inverse and that the product of a number and it’s multiplicative inverse is 1
3.multiplicative inverse

# data[].attributes.body
•Before watching the video, I knew that you cannot divide by 0.

•After watching the video I learnt that  and that 0 has no multiplicative inverse and the multiplicative inverse of a number is 1 over the number. I also learnt that 1 can equal to 2. In addition, I found out that some rules in math have been broken such as find to the square root of a negative number.

•A new term that i learnt was multiplicative inverse.

# data[].attributes.body
1. I knew that dividing by zero will cause lots and lots of problems and rules broken, such as 1=2 as stated in the video, and that either dividing by zero is completely impossible, or that our mathematics were not yet advanced enough for it. I also knew that anything +/- by zero will still be the same number, and anything times zero will be zero.

2. I learnt that the concept of dividing by zero is that having x divided by zero (a process) will most likely be infinity (another longer process), and that also 1 may be equal to any number possible, maybe even infinity or Graham's number, according to the concept of x/0=(infinity). I have also learned about the concept of the multiplicative inverse and how to find out multiplicative inverses of numbers other than zero.

3. Multiplicative inverse of a number and

•I knew that I could not divide something by 0 as it would just be 0 before I watched the video.

•After watching the video, I learnt that 0 has no multiplicative inverse. I also learnt that the product of any number except 0 and it’s multiplicative inverse is always 1.

•The new terms I learnt were multiplicative inverse and distributive property.
