Answer. •. 12 comments. ( 126 votes) Upvote. Downvote. Flag. Mr. Millette. 12 years ago. 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 that works...

- 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...

Quadratic equation. The values of x that satisfy the equation are called solutions of the equation, and roots or zeros of the expression on its left-hand side. A quadratic equation has at most two solutions. If there is only one solution, one says that it is a double root. If all the coefficients are real numbers, there are either two real ...
