It is true but we could change it and break the rules

That there is not multiplication inverse of 0

However, after watching the video, I got a deeper understanding behind the reasoning as to why numbers cannot be divided by 0.  It is because every number that is multiplied by a no. (eg x), it will have a multiplicative inverse and in this case it is 1/x. For example if 2 (the original number)x 5 = 10(new number) , 2 is being multiplied by 5. To get 2 from 10 through multiplication, you have to multiply 10 by 5's inversion (1/5) to get 2. Another method is dividing 10 by 5. When you multiply 5 by its multiplicative inversion (1/5), the result is 1. Thus it means that 1 divided by 1/5 is 5. Now lets replace 5 with 0. 0's multiplicative inverse will be 1/0. Using the rule that every number multiplied by 0 will be 0, the result of 1/0 x 0 will not be 1 and thus 0 does not work in the same way as other numbers in terms of division. However if it is said that anything divided by 0 is infinity because of the fact that a number divided by a lower number gives a higher number (eg. 10/2=5 vs 10/ 1/2 = 20). To test this out  it will be set this way. If infinity is 0's multiplicative inverse, 0 x infinity will be 1. According to this theory, to get 2 you should: (0 x infinity) + (0 x infinity) = (0 + 0) x (infinity)= 0 x infinity. However 0 x infinity is already said to be 1 based on this theory, not 2. 1 is not = to 2 and thus any number divided by 0 is not possible

I thought dividing a number by 0 was not possible because a number cannot be split into 0 groups and thus no number could be divided by 0

# data[].attributes.custom_properties.7TXGjzv4
That zero has no multiplicative inverse.

# data[].attributes.custom_properties.Ol-Iey_g
Multiplying is cloning a number for a certain number of times. 

# data[].attributes.custom_properties.7TXGjzv4
It may be possible to divide by 0 but it is not that useful 

# data[].attributes.custom_properties.7TXGjzv4
I learnt that any number divided by 0 does not always result in an error. Instead, it ends up as infinity as the smaller the divider is the larger it gets so the number is infinity.

# data[].attributes.custom_properties.Ol-Iey_g
I thought division was like the opposite of multiplication. For example: 7x2 is the opposite of 14/2.

# data[].attributes.custom_properties.7TXGjzv4
I realised you cannot divide by zero and it has no multiplicative  inverse

# data[].attributes.custom_properties.7TXGjzv4
I learnt that mathematicians found a way to discover the value of the square root of a negative number.

# data[].attributes.custom_properties.Ol-Iey_g
I thought that nothing could be divided by zero as when you divide a number by a different number, you split it into groups. I don’t really know how to explain this, but an example is 15/5 When u divide 15 by 5, you split 15 into groups of 5. When you divide 10/1, you split 10 into groups of 1. Even when you divide 10 by 0.1, you split 10 into groups of 0.1. But zero equals to nothing, and you cannot divide any number by nothing.

# data[].attributes.custom_properties.7TXGjzv4
Division is not always cutting objects into pieces. Likewise, we cannot dived 10 by 0. I will explain. If 10 divided by 1 is 10 and 10 divided by 1/2 is 20, 10 divided by 0 theoretically could be ♾. But here is the part which proves this entire theory wrong: If 10 divided by 0 is infinite, the multiplicative inverse should be 1/0. So, since 1/0 ✖️anything is =0, we know that zero has no multiplicative inverse, hence proving the theory entirely wrong. We can’t dived something without a multiplicative inverse. Right??? That’s the same thing for zero. In conclusion zero cannot be divided for it has no multiplicative inverse.

# data[].attributes.custom_properties.Ol-Iey_g
I thought all division is just basically cutting an object into pieces. For example there are 10 slices of pizza 🍕 and there are 5 people who are equally hungry. So if we dived the 10 slices equally among the 5 people we will get 2 slices per person and everyone will be happy. 10➗5🟰2  

# data[].attributes.custom_properties.7TXGjzv4
1. I am very confused.
2. The logic behind the division of 0 just doesn’t work out, and math is all logic
3. I do understand division in general a bit better though

# data[].attributes.custom_properties.Ol-Iey_g
Dividing basically is finding how many groups of x is needed to make y. Eg it takes 3 groups of 2 to make 6 ( 2+2+2). But because 0+0=0, no matter how many times you add 0, it will never amount to anything bigger so finding how many groups of 0 is needed would be impossible.
Quite honestly, i thought 10/0 would give you 0

# data[].attributes.custom_properties.7TXGjzv4
Frankly not much except that dividing by zero is still impossible 

# data[].attributes.custom_properties.Ol-Iey_g
I thought that division meant how many of ( x ) is inside ( Y ) so having an absence of something inside something was impossible.

# data[].attributes.custom_properties.7TXGjzv4
It’s impossible to divide by zero. If we say that 0*infinity = 1, then (0*infinity) + (0*infinity) = 2. But if we simply that equation, we get (0+0)*infinity = 2
Which technically means 1=2, which is not mathematically correct . I now have a deeper understanding of the concept.

# data[].attributes.custom_properties.Ol-Iey_g
Numbers Cant be divisible by zero, as each time they are taking away zero from that number, so there is an infinite amount of times they can take away zero

# data[].attributes.custom_properties.7TXGjzv4
I better understood the correlation between different numbers when they are divided and how mathematicians ascertained if anything can be divided by zero 

# data[].attributes.custom_properties.Ol-Iey_g
I though I had a clear understanding of how division works 

# data[].attributes.custom_properties.ROMmuW2I
I learnt what a multiplicative inverse is
