First we need to recognize that any form of infinity is just a mathematical construct. We are not ever going to have to deal with actual infinities, but what is very useful is understanding limiting behavior as something or other goes towards infinity. It is here that the difference between countable and uncountable infinities matters immensely. ; countable : can be put into a one to one correspondence with the natural numbers ; uncountable : cannot be put into a one to one correspondence with the natural numbers
Infinity.
infinity many
An infinity of real numbers.
An infinity of numbers between the two.
An infinity. There is an infinity of numbers between any two numbers. I you want whole numbers, there are 31.
The Webster's definition of infinity is an endless amount. The Webster's definition of uncountable is inconceivably numerous. However, infinity is the proper term to be used in mathematics.
There are an uncountable infinity of numbers between 7.39 and 7.4.
The word 'some' is used as a quantifier when the thing you're referring to is uncountable, or the quantity is not known. Whereas, the word 'few' is used when the thing you are referring to is countable or is in finite quantity
The word "all" is used with countable or uncountable nouns to refer to 100% of many things. For example: All of my furniture is from Ikea. (uncountable) I bought all of my plates from ABC department store. (countable) The words "whole" and "entire" mean 100% of one thing. It is used with countable nouns. For example: I ate the whole pie by myself. I'm so full right now. I spent the entire day watching TV and drinking beer. It was great!
all finite set is countable.but,countable can be finite or infinite
A countable set is defined as one whose elements can be put into one-to-one correspondence with elements of the set of counting numbers or some subset of it. A countable set can be infinite: for example all even numbers. This raises the strange concept where a subset (positive even numbers) has the same cardinality as all counting numbers - which should be a set that is twice as large! Even more confusingly (perhaps) is the fact that the set of all rational numbers also has the same cardinality as the set of counting numbers. You need to go to the set of irrationals or bigger before you get to uncountable sets. So you have the weird situation in which there are more irrationals between 0 and 1 than there are rationals between from 0 and infinity (if infinity can be treated as a value)! There is a minority definition of countable which means containing a finite number of elements as opposed to uncountable meaning infinitely many elements. However, these definitions are essentially the same as the finite sets and infinite sets and so there is little point in using them.
infinite(y) means forever and uncountable means unable to be counted.
Zero is nothing, infinity is everything.
The difference is infinity. Infinity is the concept of the largest possible number. Even if you take 20 away the number will still be infinity.
The terms "fewer" and "less" are often confused, but they are used differently based on what they describe. Here’s a clear breakdown of the difference: Fewer Usage: "Fewer" is used with countable nouns—things that you can count individually. Examples: "There are fewer apples in this basket than in that one." (Apples are countable.) "She has fewer books than he does." (Books are countable.) "We need fewer chairs for the meeting." (Chairs are countable.) Less Usage: "Less" is used with uncountable nouns—things that cannot be counted individually and are typically measured in terms of volume, amount, or degree. Examples: "There is less water in the glass." (Water is uncountable.) "She has less time to complete the project." (Time is uncountable.) "We need less sugar in the recipe." (Sugar is uncountable.) Summary Fewer: Used with things that can be counted (e.g., apples, chairs, books). Less: Used with things that cannot be counted individually and are measured in bulk or degree (e.g., water, time, sugar). Examples in Sentences Fewer: "There are fewer students in the class this semester." Less: "There is less noise in the library than in the cafeteria." Using "fewer" for countable nouns and "less" for uncountable nouns helps ensure clear and accurate communication.
The Lebesgue integral covers a wider variety of cases. Specifically, the definition of hte Riemann integral permits a finite number of discontinuities; the Lebesgue integral permits a countable infinity of discontinuities.
