- The way I explained it to my 7th graders is this: If 0/0 is equal to a number, then let's rewrite it as a multiplication. 0/0 = 0 ==> 0 * 0 = 0, so...
- You ask for an example of negative infinity, but what is an example of infinity? Because infinity is not a real number (it basically means 'goes on...
- We actually have that: it's called the real projective line. It's kind of like wrapping the two ends of the real number line and declaring that the...
- Well.....if you ask me, I think 0 is not really an intersection, but a bridge between positive and negative numbers and the 2nd question, 0+-∞.
- Okay, let's accept the fact the x/0=x but accepting it leads to all sorts of contradictions, Consider V=S/T (Velocity=displacement divided by time)...
- if you go and check a calculator it will show 0 and if you even think square root means its asking to what number we should put ^2 that the number...
- I like to think of it this way. When you are dividing say, 7/0, you are dividing it by nothing, but into a number of groups, which in this case wou...
- You have hit upon a field of mathematics that is called "continued fractions". Although I know it exists, it is far beyond my knowledge at this poi...
- Hi, Infinity is a concept. We cannot put a value on infinity because there will always be something bigger that we can come up with. We tend to thi...
- It doesn’t work that way. You can think of division as finding the missing part to a multiplication problem. For example, 20/4 can be written as 4...

- 0/0 is undefined. If substituting a value into an expression gives 0/0, there is a chance that the expression has an actual finite value, but it is...
- I'm just stating what Sal said in the video, but some people say that 0/0 is obviously 0, since 0/4, for example, is zero. They say zero divided by...
- 1. Separating into n pieces means that you need n new pieces to get the original piece. If you separate into 0 pieces means that you need 0 of the...
- Zero isn't a symbol. It is a number just how 1 or 45 is. Just how every number tells us the existence of something, zero tells us the existence of...
- In real life, there is no reason to divide something by nothing, as it is undefined in math, it has no real applications in the real world. But in...
- The Multiplication Property of 0 tells us that any number times 0 = 0. If you turn that into an equation, you have: x*0 = 0, where "x" is any numbe...
- Essentially, yes. This is why 0/0 is considered indeterminate - there is no single agreed upon solution.
- "What? At 2:21 wouldn't 0/0 be left as indeterminate, not undefined?" It is about time logicians go for solving the sum and they are the same as un...
Learn why division by zero is undefined and contradictory in mathematics, and how it relates to infinity and vacuous truth. See examples, explanations, and a \"proof\" that 2=1 using division by zero.
Learn why division by zero is not defined and what happens when you divide by zero. See examples, facts, and frequently asked questions on division by zero.
In mathematics, division by zero, division where the divisor (denominator) is zero, is a unique and problematic special case. Using fraction notation, the general example can be written as , where is the dividend (numerator).
Dec 10, 2023 · Learn why 2 divided by 0 is not defined and what it means in decimal, fraction and percentage. See the long division steps and a calculator for other divisions.
