If you're doing this (NB: the usual terms there are "plane" and "half-plane), then these areas are identical (in the sense that both have measure equal to the measure-theoretic infinity, and both have the same cardinality). One positive integer is 7 less than twice another. and (infinity times infinity) /2 regard as a triangle with endless boundaries also ? Come join us! Do you have a math question? But again, even in these cases "infinity" isn't an actual number. But that’s an illusion because there is no middle between negative infinity and infinity, or you could say that any point on the x-axis is the middle. If you do, you arrive at all sorts of contradictions. But overall there aren’t more numbers unless we include the irrational numbers, the “decimals that go on forever”. What does Infinity Minus Infinity Equal? Heck, it's not even infinity times infinity. It can be a helpful concept in mathematics, but you can't treat "infinity" as an actual number. I am art student want to know more about maths! how much money would i have if I saved up 5,200 for 6 years? In this sense, the set of all hyperreal numbers *R = [-infinity,infinity]. Intuition plays a big role in understanding concepts of infinity. And more. EDIT: Somebody else brought up the topic of cardinality. With this definition, there is nothing (meaning: no real numbers) larger than infinity. I think the answer depends on which math class you're in. You can sign in to vote the answer. There ARE ways to make 2 infinite numbers where one is clearly bigger than the other. Thanks everyone!!! I think I made a mistake in the question, basing on my primary thought in my mind. , 1/2, 145.9879845. . If you do, you arrive at all sorts of contradictions. That's impossible. . Zero might also seem like a good choice because it looks like it’s in the middle between negative infinity and infinity. Infinity is NOT a number. There is a bar occupy 1 unit in axis x with endless height? Assume, the better the target is, the longer the time to be spent on the target. If the area of a rectangular yard is 140 square feet and its length is 20 feet. Trump makes subtle tweak to his famous 2016 slogan. It depends on what you mean by "real". The argument is set-theoretic. However, to multiply these sets by a whole number doesn't change the cardinality, so 2* infinity = infinity. When we talk of infinity; we are speaking about really very large numbers. At first, you may think that infinity subtracted from infinity is equal to zero. In terms of everything you will likely see unless you decide to study mathematics in grad school, infinity is not a member of the real numbers, so 2 * Infinity is not a valid operation since * works only for real numbers in that definition. My Maths knowledge is too weak.. No, (infinity)^2 is the same as infinity. If you're in high school, infinity isn't a number, just the idea of an uncountable amount of numbers. No, all of the expressions you described are just "equal to" infinity. can i regard infinity times infinity as a square with endless boundaries ? https://twitter.com/TPointMath I am confused. Case 1 is like this, we like/love something / someone (just 1 entity / person) forever ( given an infinite time ) Case 2 is like this, we can like/love the better and better something/someone as time goes by (also given an infinite time), without giving up the previous likes/loves. but i found someone raised an infinity - infinity conceptual question in the link. Or Case one is just a straight vertical line ? EDIT: I should explain what I mean by 2^(infinity) since infinity is not a number. 'Tiger King' star Carole Baskin comes out as bisexual. Only in this special construction is infinity treated "like a number." It's true that in higher-level mathematics you get into concepts like "countable infinity", "non-countable infinity", "aleph-0", etc. Infinity means a number still larger than whatever we can think of. Just like an triangle ?? An extension of the reals called hyperreal numbers, denoted by *R, consists of the real numbers, R, with two additional elements, -infinity, and infinity. Thus both the "square root of infinity" and "square of infinity" make sense when infinity is interpreted as a hyperreal number. Top U.S. Marine under investigation for racial slur However, in Cantor's aleph system, 2^(infinity) is larger than the original infinity in the sense that it has higher cardinality. Get your answers by asking now. Infinity is NOT a number. There are two to the power of infinity of those, that is, 2 x 2 x 2… multiplied infinitely many times. After all, any number subtracted by itself is equal to zero, however infinity is not a real (rational) number. See that there is more than one kind of infinity. It can be a helpful concept in mathematics, but you can't treat "infinity" as an actual number. No, (infinity)^2 is the same as infinity. The argument is set-theoretic. http://math.stackexchange.com/questions/1720666/concept-of-infinity-infinity-infinity. There is no such thing as a largest number, because you can always add 1 to that number and get something bigger. Looks like you're using new Reddit on an old browser. Infinity is only a CONCEPT. Press question mark to learn the rest of the keyboard shortcuts. Hi Dana, It depends how you define "infinity''; after all, infinity is a trickier concept than "three'' or "seventeen''. If you're in college, different sets have different cardinalities.

However, in Cantor's aleph system, 2^(infinity) is larger than the original infinity in the sense that it has higher cardinality. But in this case you're dealing with "cardinality", the concept of mapping some infinite set to some other infinite set in for example a 1-to-1 correspondence. Infinity is only a CONCEPT. It is often denoted by the infinity symbol ∞.. Cardinality offers a way to compare different infinite sets, but it's still not treating "infinity" as a number. I know it's not very maths now, but still hope for answers ! The set of real numbers [infinite] has more elements than the set of integers [infinite]. (Yes, I'm sad to say that ad with the guy in the suit sitting with the kids is lying to you.) Infinity isn't really a number, it's a concept, so it doesn't behave like a number. Now if can make a mapping from every item in grid A to an associated item in grid B, then they are the same "size". EDIT: I should explain what I mean by 2^(infinity) since infinity is not a number. Can you help others with their math questions? my twitter: @tweetsauce my instagram: electricpants Sources and links to learn more below! can i regard infinity times infinity as a square with endless boundaries ? We have 2: grid A and grid B. So we can imagine infinity*infinity as a 2d grid where the axis are the natural numbers. Imagine there is a square and triangle which their sides are with infinite lengths, then the area of the square is bigger than the triangle ? Find its width.? and all the real numbers (numbers like 1.23456436435. . The classic example is trying to compare the magnitude of natural numbers to the magnitude of real numbers.
